Krypton is for Adventurers

Krypton (the planet that is, not the element) is mostly known for blowing up--that and giving us the baby that would grow up to be Superman. But in Superman #239 (1971) E. Nelson Bridwell designed maps of Krypton appeared, revealing it to be one hell of a place to adventure.

Let’s take it by hemisphere. Here’s the “Old World” first:

1 Striped River: Simply a two-toned river? Surely not! I bet these are two different fluids with two different dangerous ecosystems. Swim away from a purple water shark, right into the jaws of a magenta river shark.
2 Erkol: “Oldest City on Krypton”--which means of course, ruins...and treasure.
3 Fungus Caverns: Yes, please.
5 Ruins of the Ancient City of Xan: See (2) above, except this city looks even more ruinous.
6 Mt. Mundru: The highest peak on Krypton probably has some monastery at the top where monks are waiting to teach their martial arts skills--and esoteric wisdom, but mostly the skills. Or maybe there are just Kryptonian yetis.
7 The Glass Forest: Where even mundane flora and fuana become dangerous thanks to their razor-sharp glass edges, and their habit of turning into a shower of shards when destroyed.
8 Jerat: “The Ghost City” offers two intriguing possibilities. It could be a city inhabited by ghosts, or the ghost of a city, whichever fits your challenge rating, or whatever the kids call it.
9 Vathlo Island: This “highly developed black race” is probably like elves crossed with Parliament. Or maybe like the super-scientist Globetrotters on Futurama. Whatever, so long as their key features are “black” and “highly developed.”

The “New World” Hemisphere starts off with a bit of a let down, because...

1 Kandor: isn’t there anymore because its in a jar at Braniac’s place. Maybe the dungeon’s beneath Kandor are still there, though.
4 Fort Rozz: is probably run by an AI which will go crazy, and turn the installation into a trap-filled Fort of Horrors.
5 Atomic Town: seems to be shaped like a pentagram, so is probably a gigantic sigil for summoning a nuclear horror. Probably Azathoth.
6 Jewel Mountains and 8 Gold Mountain: Sort of “Monty Haul,” but that was Bridwell, I guess.
7 Rainbow Canyon: An idyllic land of freedom from care--or one constant Prismatic Spray?
13 Bokos: The island of independent thieves--which suggests this is a guild-free shop. Maybe its like the city of thieves from Adventure Time and everybody who enters the city eventually becomes a thief?
14 Magnetic Mountains: In other words, you’re gonna regret getting the full plate.
