Single Axis Outer Planes

There are a lot of very reasonable criticisms regarding the Gygaxian Great Wheel of Outer Planes, though I also like a lot about it. I've spent a fair number of posts on this blog trying to make it truly it some sort of coherent set of competing paradigms as Planescape promises but doesn't really deliver.

This post, I want to go in another direction entirely and see if the Outer Planes can be configured in such a way as to have a bit more Medieval flavor, a possible monotheistic bend, and potentially mostly be about the afterlife.

Take a look at the cosmology presented in the works of Dante:

Dante (like OD&D) imagines an order where what in latter day D&D terms we would call Lawful Good. So the Empyrean, the realm outside the cosmos where the Godhead or whatever supreme principle of goodness resides is the equivalent of the Seven Heavens of Mount Celestia in the Great Wheel.

"Beneath" that we enter the cosm and the spheres of the heavens. Here mystical cosmology mixes with physical cosmology and we have the Aristotlean celestial spheres of the classic planets. Dante makes of them "not-quite-good-enough heavens, and I would too, but with a twist. These would be the afterlives or mystic realms of "pagan" deities (using the term here to mean deities other than our Supreme Godhead mention above). Something similar to how the cosmology of the Sandman comics series works or Jurgen by James Branch Cabell, but more systematized as Gary would have wanted it. I would probably nix specific alignments in this sort of setup, focusing on interesting themes and correspondences.

Above the planets is the sphere of the Primum Mobile or Prime Mover. This will be the mindless demiurge or ghost in the machine that makes the physical and near physical universe run. This is Mechanus of the Great Wheel.

 

Arriving at the Earth, we find Elysium/Elysian Fields, the Terrestrial Paradise. It can be found by the living, but it's difficult. Beneath the Earth is the gloomy, gray realm of Hades. 

In the caverns beneath Hades we begin to slip into the realm of truly evil souls, places where monsters have been cast down. There realms are probably all tied to a Deadly Sin. No doubt there are several infernal realms before we get to Hell (represented the sin of Pride) proper, where the rebellious angels have built their resentful kingdom in exile.

Immediately beneath heal would be Tartarus, where the Godhead has locked up frightening beings. Rival gods? The mistakes of former creation? Who knows?

Beneath Tartarus is the Abyss. The deep waters mentioned in Genesis, though this may not literally be water but some fluid. Liquid Tiamat (from Babylonian myth, not the the Dungeon & Dragons cartoon). Malign chaos incarnate.

Greyhawk: Medegia

The See of Medegia is a territory ostensibly within the Great Kingdom of Aerdy that is under direct sovereign rule of the Holy Censor of the Aerdian Church of Law. Though the reach of the Censor's ecclesiastical authority has diminished with the decline of the Great Kingdom, he remains one of the most powerful and wealthy rulers in the eastern Flanaess.

The Church of Law has ever tied to the Aerdi, their kings, and kingdom. While the various Hierarchs of Law of the Flanaess were independent, they were in communion, and the Hierarch of Medegia was invested as Holy Censor, guardian over the doctrine of Law and moral guide to the Malachite Throne and the entire Kingdom.

Most Medegian church houses, including its great basilica, were originally dedicated to Pholtus, the Blinding Light, though Legalism being a transtheistic faith, this was not true of other churches in other lands. Today, the iconography of Pholtus persists, but the stern-faced deity is little favored by the current Holy Censor, his most senior clergy, or the other highfolk of the land. The Divine Law has varied manifestations and champions, so why should they not pray to Zilchus, whose doctrine of material prosperity for the faithful is more amiable to their wealth and privilege?

Despite the Holy Censor's roll as advisor to the Overking, neither the indolent Hierarch nor his flattering and generous orthodoxy are favored at court. Ivid is rumored to have become enamored of an antinomian heresy wherein, as a divinely favored monarch, he is above the precepts that bind others. The Censor is, of course, concerned, but not overmuch, so that his enjoyment of his position isn't soured.

The Hidden Religions of D&D: Druidism

This one isn't so much hidden, but hey, when you've got a series title, you gotta stick with it. Unlike with the Church of Law which has been obscured by tme, I think people have a good idea of what Druidism in D&D is: it's neutral and associated with Nature. In the Greyhawk setting and other places it's the "Old Faith" standing in perhaps for pre-Christian beliefs of Europe but without the Christianity.

I think there's another way to go, though, completely consistent with what the original works tell us about druids.

Druids first show up as monsters in the Greyhawk supplement. We are told they are "priests of a neutral-type religion." They can shape change and attractive barbarian followers.

They become a class in Eldritch Wizardry where they are described again as Neutral and "are more closely attuned to Nature, serving as its priests rather than serving some other deity." Mistletoe is holy to them, and they protect plants and animals.

Neutral may well just have been meant to imply unaligned here--not taking a side in the conflict between the civilizing force of law and the destructive forces of chaos: "I am not altogether on anybody’s side, because nobody is altogether on my side, if you understand me: nobody cares for the woods as I care for them," as Treebeard would have it. But maybe it's not just the woods the druid cares about?

Unlike Law and Chaos which seem to be transcendent and come from extraplanar forces, maybe Nature in this context is the cycles and balance of the material world? Given the description in Eldritch Wizardry, it seems likely to me that the religion of the druids is pantheistic with Nature (or the material plane) being an immanent divine force or deity. It could be animistic with everything in the natural world having a separate spirit, but it might also be monist, where divine Nature is the only true reality.

I think then that the druid's neutrality is a somewhat militant sort. The dualism of Law vs. Chaos is contrary to their understanding of the unity of all things; the strong, opposing polarities are nonsensical if existence is governed by cycles. Worse, these ideas from the Outer Planes would be alien intrusions on the harmony of the world.

Thinking Greyhawk

Over the past month, I've been reading some historical fantasy (Between Two Fires and His Black Tongue), some straight historical stuff (rpg supplements from Codex Integrum and the season on Frederick II of the podcast History of the Germans), and most recently, taking a real look at the World of Greyhawk (1980) folio.  All this stuff knocking around in my head led me to believe it might be interested in borrowing an old idea from Miranda Elkins and doing a series of blog posts developing a version of Greyhawk derived from the folio, with a Medieval history sort of feel.

I'll be using the 1980 folio as the only "canon" though I'm not opposed to taking material from the 1983 boxset and the Dragon articles written between and around the time of both publications. I'm trying to avoid more recent Greyhawk material. In keeping with the other recent inspirations, I'm going channel the historical wargamer Gygax over the pulp fan Gygax, and also I'll be using some of the ideas derived from examination of the pre-Greyhawk implied setting of D&D.  

L. Sprague de Camp: Most Gygaxian Fantasy Writer?

I don't know Gary Gygax's preferences in regard to authors of fantasy fiction, but I feel pretty strongly that L. Sprague de Camp (1907-2000) is the closet in sensibility to Gygax himself, at least in the earlier days of D&D. 

De Camp makes several appearances in Appendix N. I haven't read all of these works, but the ones I have read demonstrate some characteristics I get from Gygax's worldbuilding and from his early fiction that I have seen. There is some content similarity (like universe-hopping, crossovers with the works of other authors, and hierarchical planes of existence), sure, but what I'm mainly thinking of is more of a structural or attitudinal alignment. 

For one thing, I think it's fair to say that Gygax's work shows a concern with realism and degree of pedantry around certainly topics: Extensive list of polearms, obscure terminology, etc. De Camp gives us an extensive exegesis of REH's naming in the Conan stories and also an analysis of the same stories' technology. He wrote a series of Sword & Planet stories (the Krishna series) that makes a point of addressing the unrealistic elements of Burroughs' and others' similar stories.

It seems to me there was a logic to Gygax's D&D work. I'm sure this is in part due to it being in a game where you have to be prepared for player action, but it resembles the application of rational consideration of elements in fiction as in the Harold Shea stories or The Carnelian Cube.

Both men also have a fondness for humor in their fantasy. While this isn't an uncommon trait and is found in the work of a number of Appendix N or adjacent authors, I feel like use of anachronism for humorous purpose is something found in Gygax's work that also occurs in the Harold Shea series. Less than totally heroic or unheroic protagonists (often the humorous effect) probably describes a lot of D&D, but also several of de Camp's Krishna novels and his Reluctant King trilogy.

As to Gygax's later work, I've only read a couple of the Gord novels and that was decades ago, but I don't recall them being particularly de Campian. Maybe his sensibilities shifted over time or perhaps they reflect a desire to better compete in the fantasy market that existed in the mid-80s. Still, I think on balance, the similarities are there.

The Hidden Religions of D&D: The Church of Law

Thinking about rationalization of the implied setting of D&D, not in the way of industrial magic or anything like that (though I've done that before) but in the direction of how the implied setting of D&D might point toward its religions or belief systems. Sure, there's the explicit fantasy polytheism, but as others have pointed out, it's undermined by the (at least up through AD&D) presentation of the cleric class as vaguely sort of Medieval Christian and by the fact that historical polytheism didn't work like D&D thinks it does. As Delta puts it:

...D&D claims to have a polytheistic religion, but you've got both the politics and the critical Cleric class set up as in the medieval Christian world, and nowhere else.

Is there a more interesting and perhaps more realistic way weave together the elements presented? I think so.

Note that Clerics of 7th level and greater are either "Law" or "Chaos", and there is a sharp distinction between them.
- Gygax & Arneson, Men & Magic

OD&D mentions Law and Chaos with regard to a cleric's orientation. To me, this suggests a system of belief with a dualist cosmology. (Perhaps this is the actual state of the cosmos, but it doesn't have to be!) This is a moral dualism, as the two opposing forces or principles are in conflict. This could be interpreted (and perhaps is by some sects or particular faiths) as ditheistic with two gods or groups of gods in opposition, but I also think the broader, philosophical tradition could embrace transtheism, where the existence of Law and Chaos is a greater and more important truth than the existence or nonexistence of god-like beings/powers. 

The church of law is syncretic, incorporating deities as it grows as agents, exemplars, or aspects of Law. No doubt there would be historic disagreement (possibly even conflict) over just how much deference and attention these powers are rightly due.

Clerics/priests, given the hierarchical structure presented in OD&D, are important in public rituals and ceremonies of the belief system but are also likely interpreters and scholarly experts on Law. Each of these Patriarchs (and Matriarchs, probably, though OD&D doesn't mention them!) is independent and self-governing but in fellowship with the others (generally). Initially a Patriarch would be a charismatic leader who attracts followers, but presumably the church they founded would have a mechanism of choosing a successor. 

Patriarchs are the final arbiters of the commandments of Law within their area, but the Patriarchs of the various churches might vote to decide points between them, or perhaps different interpretations would reign in different jurisdictions. Another aspect of the high clerical function extremely relevant to adventuring is calling for and supporting crusades/jihad against Chaos. 

Speaking of Chaos, it does seem a bit odd it is presented with a hierarchical clerical structure identical to Law's. One possibility is the "anti-clerics" are sort of Satanists and just performatively mock the church of Law, but another possibility is that "Chaos" only speaks to its ultimate goals or cosmological beliefs, not to its organizing principles. It's also possible (even likely) that the Church of Law applies the name Chaos to a diverse group of belief systems that don't agree with it and often don't agree with each other. 

Weird Revisited: Mondegreen's Mixed-Up Magics

In the Land of Azurth, the wizard Mondegreen is infamous among magical practitioners, not because he was powerful (though he was) nor for his output of arcane scrolls (though it was prodigious) but because of his habit of misprinting magical sigils and formulae. He seems to have suffered some sort of malady in this regard, perhaps a curse.

A Mondegreen scroll will not contain the traditional version of the spell it appears to catalog at cursory examination. The subtle errors will either effect some aspect of the spell 50% of the time, giving:

1 Advantage to the spell save
2 An increased duration
3 Increased damage (if applicable)
4 Decreased damage (if applicable)
5 A decreased duration
6 Disadvantage to the spell save

The other 50% of the time, it will not work as it should, but rather produce a magical effect from a roll on the Wild Magic Table.

Where'd the Grot Go?

Watching Delicious in Dungeon and Frieren: Beyond Journey's End (which are both great, so watch them), I've noted that both display very D&Dish world, but ones completely without even token gestures toward the gritty and grime of Medievalism. They are grot free, nothing like this to be seen:

This could be put off to the style of anime or cultural differences between U.S. and Japan, but I noted this same thing back in my review of Dungeons & Dragons: Honor Among Thieves. Compared the production design and costuming of that film to something like Excalibur (which is pretty gritty despite all that gleaming plate) or even Jackson's Lord of the Rings. 

I think it's even in the art of a number of 5e products, too, and in The Legend of Vox Machina animated series (at least the parts of it I've seen).

I'm sure there are counter examples, but these are fairly high profile works in the D&D world, some of them official, so I think we're in a moment where D&Dish fantasy worlds partake of more of a fairytale feel, perhaps, in regard to depict of their environments. Nothing wrong with that, really, just an observation.

The Elements of Generic D&D

Over the years since its creation, the standard mode of D&D has become a subgenre of fantasy unto itself, codified now in the other rpgs that followed on its coattails and the other media they've inspired. GURPS terms it "Dungeon Fantasy," though I don't think it required dungeons--though obviously they play a big part.

The essential element as I see it are:

• The primary characters are a loose group of companions.
• Well-defined character roles/types and capabilities, very often recognized within the fictional world.
• Characters engaged in quests or missions in dangerous locales, mostly commonly underground. 

Other elements that are common are:

• A setting with pre-modern technology.
• Adventurers as a recognized role in society.
• A large variety of monsters, categorized and taxonomized. 
• Hierarchies of capability within character types.
• The development of character abilities and capabilities over time through dangerous trials. Sometimes there are in-setting codified tiers or levels.

There are, of course, others but these are things I feel like are less common in fantasy works that aren't in the subgenre than those that are. There may even be some work that if you play loose enough with definitions that would fit all of the above that we wouldn't consider "D&D fantasy," but genre boundaries have never been impermeable and precise things.

Got to Catch Them All

Inspired by Vance mostly, people have considered spells as living entities. It was discussed in the Gplus days, and it shows up in Eric Diaz's Dark Fantasy Magic. Back in 2011, before I had really read a whole lot of Vance, the Vancian magic of D&D and the film Pontypool got me imagining spells as a neurolinguistic virus or memetic entity.

Anyway, all that as preamble to a related idea which I'm sure someone has had before but came to me seeing my daughter play Pokemon Go. If spells are living things in some fashion and wizards are forced to adventure to find them and master them, aren't they kind of like Pokemon? Eldritch viruses or self-assembling arcane subroutines. Free-living (at least currently) cheat codes to the universe. Things to be captured and tamed and bent to will of the mage.

I think this sort of framing could make the finding and learning of spells on scrolls more interesting (or at least more challenging), and I think it would definitely suggest interesting things that could be used to develop the background the campaign world.

The Cleric and the Rituals of Faith

Over the weekend, I read this interesting blog series about how polytheism worked in the real world. Check it out. 

Anyway, it got me thinking about how D&D/rpg polytheism might be made more realistic without changing it much. Granted, it's a bit of an uphill battle since rpg polytheism of the D&D variety is very unrealistic in a lot of ways, but I'm going to focus here on one thing and that's Devereaux's central point in the early articles: religion is mainly about ritual not metaphysics.

This is actually pretty good for the D&D cleric, because they are largely soft on metaphysics and philosophy (short a lot of worldbuilding) but out-of-the-box do a lot of things like spells and special abilities that could be glossed (and roleplayed) as rituals. It's sort of transactional, even mechanistic from a modern lens, which is good for D&D because that's what clerical magic is. 

So, clerics are the most religious (in what Devereaux relates is the Roman sense) because they have the most effective deity-related rituals (spells) and they are the most diligent in their performance (it's their job). The use of the cleric to the adventuring party is this very religiousness: their ritual performances always get results. 

I think it would take relatively little roleplaying in this direction and reframing of these abilities in a more religious ritual context to make it feel a lot less merely mechanistic and a lot more flavorfully mechanistic.

Weird Revisited: Combat as Bloodsport

The original version of this post appeared in 2018.

 

A common reframe in the old school landscape is "Combat as War vs. Combat as Sport," often used to negatively contrast elements of 5e and particularly 4e concerned with encounter balance and "the encounter" as a fundamental unit of game action in general with the old school. Without getting into the merits of how this argument is typically framed, I think that even if we accept this as true, there is a way to lean into those elements of modern D&D and come out with something cool. Instead dungeoncrawling for treasure (mainly), maybe the dungeon environment could be the battleground of a big tournament.

X-Crawl deals with some of this territory, I guess, but from what I read of it, it is set in the modern day, and seems very much concerned with the celebrity aspect of things, bringing in a lot of professional athlete cliches. All well and good, but I'm more interested in something more like Dragonball Z. The fighters are in it often for the personal betterment--a personal betterment that is practically apotheosis, which dovetails nicely with D&D advancement. What if the gods or immortals or whatever design the dungeons as tournament grounds, and foundries to forge new exalted beings to join their ranks?

In this context, the lack of XP for gold makes perfect sense. Also, "levels" of dungeons are like brackets of a tournament. In order to give a good spectacle, you don't want scrubs advancing to take on the contenders too soon. Mainly playing this sort of setting would just mean thinking about the game differently. The only change might be that there wouldn't be any nameless rabble or humanoid tribes with kids and the like. Everybody in the dungeon is playing the game!

Et in Arcadia Formicae Sunt

Arcadia was born from the schism between Absolute Order and the Archons which believed in transcendence, those who raised up the Heavenly Mountain. The Archons of what would become Arcadia, were in awe of the Mountain, but worried its rigors would not create the optimal balance of Order and Good for the most souls. The Mountain, they felt, risked unacceptable numbers of souls potentially falling to Chaos and error in the name of a goal that might never be attainable. Only through Mechanus could the Cosmos be salvaged, but the algorithms must be modified to reflect the needs of the willful souls of the Primes. Arcadia would be that benevolent Order. 

Long ago, the greatest of Arcadia's builders distributed their being among a crafted species. The ant-like formians carry out and carry forward the great working through that divine spark within.  For the souls which come to reside in the ordered collectives of Arcadia, the formians are both humble servants and strict correctors of infractions. They model for the other inhabitants self-less service of the community.

Visitors to Arcadia find it a place of great serenity and happiness. Its souls live in ziggurat arcologies with terraced gardens and precise, geometric parks. They are amiable, though highly conformist and given to speaking in aphorisms regarding the virtues of their lifestyle.

It could be said that Arcadia is a benevolent dictatorship. While the souls have a great deal of freedom, there is little tolerance of behaviors which are detrimental to the community. Friendly warnings and lectures are the first response, then tasks meant to create awareness. If those interventions are ineffective or resisted, the community practices ostracism and a truly rebel soul will find the plane itself rejecting them.

The Structure of the Inner Planes Revealed

Back in Dragon Magazine #8 when Gygax presents the first diagram of the standard planes of D&D (which wasn't yet a "Great Wheel") he assures us the image is "a 2-dimensional diagram of a 4-dimensional concept." Gygax doesn't explain what he means (is the entire conception 4D or only some part>), and so far as I know, no one else seems to have picked up this thread. 

In Dragon #42, for example, Lafoka makes the both suggestive and hard to parse statement about travel to the Elemental Planes from the Prime: 

A figure with ethereal access can freely travel on the Prime Material, go “up” into the Elemental Plane of Air, “down” into the volcanic Elemental Plane of Fire, can go into the Elemental Plane of Water (if a large body of water is nearby), or can go “down” into the Elemental Plane of Earth. 

I think this is mainly saying that areas of the element on the Prime Material are effectively portals in the Ethereal, but it could be more clearly worded if so, and why are up and down in quotes as if they are only so-called? Anyway, unless that scare-quoted up and down are referencing directions other than the usual, this doesn't offer anything.

Next, in Dragon #73, Gygax (inspired likely by Swycaffe's article in Dragon #27, though he doesn't credit it here) proposes a cubic model of the Inner Planes to accommodate the Positive and Negative Material Planes and the various para- and quasi-elemental stuff. Still no indication of dimensions beyond three, though.

I've written posts about the much-maligned inner planes before, I've never addressed this aspect either, so now, in full recognition of what has been written about them by above, I'm going to suggest that the inner planes exist in a 4-dimensional space. So, a better model for them and their relationships would be a hypercube or tesseract (to use the word coined by Charles Hinton to refer to such). Here's a 2D representation of the spatial relationship of the 3D "faces" of the 4D structure:

So this means the elemental planes (with the Prime Material unpictured in the center) are all 3D cells accessible by travel along the 4th axis. Hinton calls these directions kata and ana, and they stand with left and right, forward and backward, and up and down, to define location in a 4D space. This video shows how the above projection is arrived at by "unfolding" the 4D shape in 3 dimensions.

Of course, the Inner Planes don't really form a 4D hypercube any more than they were a cube. It's a model to show their spatial relationships. 

Godless in the Outer Planes

The Archons of the Cosmos and their lesser progeny have the comfort (or curse) of an unshakable belief that there was something different before. Their separation and conflict is based on different ideas about how to regain what once was and what precisely the characteristics of that thing was but they know it existed.

Mortal souls, even planar dwelling ones, don't share that faith or knowledge.

Mortals on the Material Planes are generally unaware of the wider conflicts in the Cosmos, but Planar ones, particularly those dwelling in the Concordant Opposition cannot help but be aware. In the city of Sigil, very mortal philosophies have emerge or at least congregated to explain the clash of realities around them.

The Athar deny or at least doubt that the gods and Archons have any privileged knowledge of the multiverse compared to mortals. An elephant might seem godlike to an ant, they say, but it has no greater insight into how or why the sun rises. In fact, some Atharan thinkers have argued that the certainty experienced by the Powers (as they call them) is a barrier to their rational examination of the Cosmos, suggesting that, whatever their puissance, they may be less capable of reason than mortals. Athar sages see the simplistic duality of Law and Chaos with their ill-defined and contingent categories, for explain, as proof for this line of thinking.

In general, Athar adherents seek to free mortal minds from the tyranny of the Powers, for only then can anyone ever hope to understand the Cosmos. Some Atharans believe that a Godhead does exist that undergirds or perhaps created reality, but the nature of such a conceptual being is only conjectural, while others feel such assertions are at best premature.

The Plane of Whatever It is, I'm Against It

No one is quite certain how the Concordant Opposition came to be. It is quite possible that some soldiers of Law and some warriors of Chaos tired of the endless battle of natures and paradigms and came together in that consensus to make another alternative. Others believe (or hope) that it is the place where the last fragment of the Godhead exists. a strange loop of dreaming God unconsciousness, a bulwark against a schizoid multiverse. People in the City of the Sigil, in particular, like this idea.

However it came to be, it stays because he serves a purpose. It's the phase boundary between not only Law and Chaos but the other syxygies which emerged from their conflict come together. It is the place of concordant. Of course, it actively resists being incorporated into any camp (though they all try). It is a place of opposition.

Across it's expanse none the Powers hold sway, yet no where are their philosophies more discussed and debated. There are groups of evangelists and missionaries from other Planes working to convert travelers, though these all die out eventually, either in conflict or by loss of faith. The plane does not mock, but it is actively indifferent.

At the edge of these Outlands are the Border Towns. Their appearance vary from town to town, but they control the flow of traffic from whatever plane is on the other side. All are fortified, no matter how benign the appearance of the Plane on the other side. Indeed, from the perspective of the Opposition, the most benign are often the most dangerous.

The Grind of Acheron

There is a realm where the obdurate, crystalline structure of a Mechanus shatters and fragments, floating free into the void of half-formed concept. This is a border, though not any physical border because the clockwork nirvana is infinite and redundant in its mechanism, but a conceptual border where the Prime Mover's certainty no longer holds, where the grand program fails. This was the place where, after the fall from Unity (as Law sees it), rebellious Archons sundered themselves from Mechanus. This is the ideaspace separating Pure Law from Hell. This is Acheron.

It's a hell of sorts in its own right. Its acolytes know it as the Crucible. Here, they contend, new truths of Law are formed. Perhaps one day there will be one stronger and surer than either Hell or Mechanus? Adepts of Pure Law view it as gall on the purity of Order, the place where Hell's error abrades it. The Lords of Hell see it as an opportunity.

Pieces of supernal machinery break off at the edges of Mechanus, twisting and reforming, to store failing Order within, into planet-size Platonic solids which continue to degrade, erode and crumble. These have been colonized by numerous beings: malcontents from Hell, reformed things of Chaos, and authoritarian souls with iron dreams of their own version of Order. All the would-be dictators and tyrants begin to gather their followers among the lost and the beaten and forge their own armies of conquest. And then they go to war.

The struggle is as senseless as it is endless. None of the despots or authorities are ever able to overwhelm the others and seldom do they convert them. The strength of Law is shattered, after all. Also, none of them have clear vision of Unity, for they were only born after it. They merely ape what they know of Hell, crudely. 

One might be tempted to view Acheron as a place of Chaos, but philosophers point out that when taken as a whole, the plane is as predictable as Mechanus. Its war machines grind forever on at the behest of devils who will never achieve the godhood they crave.

Sword & Sandals Mystara

The Known World of Mystara is a Hyborian Age-esque fantasyland of often thinly disguised real world cultures from a variety of historical eras, but the general vibe seems Medieval to early modern. I think it would be interesting reimagine Mystara as a more ancient world inspired, Sword & Sorcery setting, though will not greater adherence to a single era. Here's how it could breakdown:

Emirate of Ylaruam: This desert region has always been oddly placed, but depending on what latitude you think it's at, it might be weird for it to be a hot desert. Maybe it's a cold desert like the Tarim Basin or the Taklamakan. You could ditch the faux Arab culture for something more Central Asian, and give it's central religion a more Eastern flavor.

Empire of Thyatis: Less Byzantium and more Rome, though I would probably move it more in a Hellenistic direction. What the Empire of Alexander might have been like if it had been able to hang together better after his death.

Grand Duchy of Karameikos: This would stll be a breakaway, former province (though not a "Grand Duchy"). There wouldn't be true, Medieval feudalism here, but something more like the Roman latifundia.

Kingdom of Ierendi: This kingdom ruled by adventurers is kind of a pure fantasy trope, but I would give its material culture a Minoan spin.

Minrothad Guilds: A plutocratic thalassocracy more like Phoenicia or Carthage. The Guilds would be collegia.

Principality of Glantri: Well, still a magocracy, but maybe more like the Estruscans?

Republic of Darokin: Keep the plutocratic republic, but cast it less as Venice and more as Republican Rome with a of the "center of caravan routes" feel like Samarkand or Palmyra. A bit of Persian influence wouldn't be misplaced as Darokin does border Sind, which is sort of Mystara's India.

The Northern Reaches would probably still just be sort of Vikings, I guess, maybe more proto-Vikings like the horned helmet wearing raiders of the Nordic Bronze Age. Ethengar might be more Scythians than Mongols. Haven't given much thought to the demihuman lands or Atraughin.
