Land of Oz
A Song of Ice and Fire "world"
Unless you've never played any Lord of the Rings game, read the books, or watched the movies you've heard of Arda. If under the name of the part of Arda where most things happen, Middle Earth.
I don't know, I like a few, Azeroth, Tyria or Nirn are up there though.
Arda isn't mentioned in any of those. You need to read more of his writings to get that name.
LotR and the Hobbit while the most... Story litterature Tolkein wrote was by far the least descriptive of the world he created.
PS I also blanked for a second "Wait, Arda? ... Oh!"
"Its the 41st millennium and there is only war..."
Warhammer 40k closely followed by the Fantasy World.
Space Elves that fly around the galaxy homeless on Spaceships the size of worlds, yeah that boss.
Dudes that drop from orbit in a metal capsule into a firefight wearing 3 inch think power armor, with a gun the size of a child, tearing shit up.
Also Dark Elves and Dark Elder are basically the most awesome 'Elves' of all Fantasies, followed closely by Mirkwood/Lorien/Rivendell Elves.
Planescape. It's a cluster**** where every world/plane of existence in DnD meet, where gods walk among demons and devils and is ruled by the Lady of Pain. Nobody ***** with the Lady of Pain.
