Middle-Oerth

The fantasy world authored by the "D&D Earth" version of J.R.R. Tolkien--his alter-ego in the Urban Arcana campaign model. (Perhaps the "Urban Arcana Tolkien" is named J.J. Rashbold, a pseudonym Tolkien used.)

Is evocative of Middle-earth, but made of D&D elements from any and all D&D worlds.

In the Urban Arcana timeline, The Hobbit novel is called The Hobni.

Uses Flanaess map, but reversed from right-to-left.

Only used for the shape of the continental shore line, not for the location of mountains, lakes, or forests.

Doesn't use any other Greyhawk features specifically, except when those are the most fitting equivalents of all the D&D worlds.

Is an alternate Oerth/Aerth/Yarth/Uerth.
