The Great Under

The Great Under, also known as the Underdark, is the pseudo-underground and extraplanar dimension that resides deep under the earthly mantle of the world. Housing all manner of drow, duergar, deep gnome, subterranean races, and aberrations, the place is known for its horrible tricks on the mind and near-endless cavern ways that weave throughout the entirety of the realm.
