Krevborna: A Gothic Blood Opera is a system agnostic setting book released this week by Jack Shear of the
Tales of the Grotesque and Dungeonesque blog. The world detailed is the sort of place Jack deals with in much of his rpg writing: an early modern setting with more than a hint of the Gothic.
Full disclosure before I delve into the review proper: I am listed in the credits of the book as I have been a player in Jack's online game (
Tobias Rune, Scientific Occultist!), and Jack has done some editing for me on my stuff in the past. We have been blogosphere friends since long before that. My view, then, is perhaps biased.
Krevborna is 109 pages plus an index. In that space it vibrantly evokes a certain type of setting, and gives you locales, NPCs, organizations, and conflicts with which to populate it. It is fashionable in many circles to say setting books should always be short or deliver things very lightly. This is an understandable reaction given the bloat that has afflicted many a "major" rpg company setting book. My opinion is this: A setting book should have exactly as much verbiage as it needs to achieve its goal (and that goal should in part include usability). This will inevitably mean that no setting book is for everybody. some people will want the exotic cultural detail of the
Empire of the Petal throne or
Glorantha, and some want a setting heavy on new mechanical tidbits, but otherwise interchangeable with any number of faux-Medieval worlds. Having written a couple of setting books myself, I can say that there are always people that think you gave just the right amount of detail and then those who want more. (There are probably also those who think I wrote too much, but they don't send me emails.)
I don't think I'm off base when I say that Jack isn't concerned with you being able to replicate
his Krevborna in minute detail; he wants you to be able to create your own Gothic-tinged, dark fantasy setting that may happen to also be named Krevborna. He is light on many details, focusing his time on directly addressing theme, tone, and atmosphere, and how you leverage these things in a fantasy game as a DM. Jack is very good at delivering these elements flavorfully but briefly. Maybe it's his college educator background, but he's able to bullet-point and not be at all dry!
I don't mean to suggest there is
no setting detail, because there are plenty of Krevborna-specific information and tools, and plenty of stuff to help players get into the mood, too: sample names by region, appropriate backgrounds, tables of dark secrets, and NPCs to be patrons, acquaintances, or antagonists. The great supernatural powers are briefly described, allowing DM's and players to flesh out the details as they will.
The last section of the book is a brief summary of Jack's approach or "house rules" for running Krevborna in 5e. This is light enough that no OGL is required, but meaty enough that those versed in the 5e rules will know what he is doing. The strength of the system agnostic approach is this can be easily ported to old school simulacra or DungeonWorld or whatever.
In summary, I think this is a great setting, but also a great demonstration of a way to present a setting, and is well worth the price of purchase.
