Editing Underdark (section)

== Other Settings ==
* In [[Mystara]], you have the [[Hollow World]], which is a pulp styled "land that time forgot" on the interior of the planet, complete with internal sun. In between the two, there's a mantle of miles-deep rock, filled with caverns that make up a more "conventional" Underdark, complete with a resident race of [[Shadow Elf|cavern-dwelling outcast elves]].
* In [[Eberron]], the Underdark is replaced by "Khyber," the Dragon Below. It's similar enough to bog standard Underdarks, except that there's there's a higher population of [[Rakshasa]]s present, trying to free their Rajah overlords. Also [[Hag|Night Hags]]. The deeper you get, the less reality makes sense.
* In [[Pathfinder]], the Darklands are a clone of Faerun's Underdark, based in part on the tiny bits of Underdark fluff that leaked into 3e's stable of [[OGL|Open Game Content]]. One of the more unique aspects of the Darklands is that its bottom realm, Orv, is composed of a bunch of large "Vaults" constructed by an unknown [[Old Ones|precursor race]] that are reasonably interconnected, but hard to get to from the middle layer, existing to scratch your party's itch for pulpy [[Mystara#Hollow World|"lost world"]] style adventures.
* [[Lamentations of the Flame Princess]] features the ''Veins of the Earth''.  Atomic bees, fossilized vampires, cosmic angler fish that use poorly written bad guys as bait, delicious fungi men, living trains festooned in weapons... the list goes on for the strange things to find down there. It also has its own take on [[Drow]] (crazy), [[Duergar]] (they think in straight lines), [[Derro]] (schizophrenic), and others.  It's not a pleasant place, but then - who expected it to be.
* [[Dragon Magazine]] #267 devotes an extensive article to examining four alternate versions of the Underdark; one in which the [[Duergar]] have taken over; one in which the Underdark is the bastion of the "good" races against a ruined surface; one in which the Underdark is mostly flooded and thusly dominated by aquatic races; and one in which the Underdark basically is a gateway to the [[Far Realm]].

Some settings barely cover half a continent, and/or have continents far disconnected from one another, so don't exactly merit the definite-article "THE-Underdark". [[Krynn]] has enormous dwarven mines linked, sometimes, with nondwarven cavern-systems; but they don't link with one another, so you won't be meeting (say) [[Taladas]] [[disir]] anywhere below Ansalon. Same goes for [[Scarred Lands|Scarn]]. The [[Larisnar|Accordlands]] have a demon-haunted underbelly but that's focused below a small region.
