Subterranean (range)
Subterranean environments include underground lairs, cave labyrinths and dungeons, where the setting is below the land's surface in a dark and dangerous place. Some of these places are merely a burrow carved into the earth, which can be explored in a few game minutes and the creatures within met almost at once. Another form is a humanoid garrison that has been built below the surface to allow raids upon the local area through providing a refuge that is difficult to find. These can develop into underground villages for races that are comfortable dwelling below ground, where crops and animals bred to the subterranean environment can be raised to provide food.
Still other subterranean places are sprawling, multi-layered palaces, protecting ancient cult, humanoids that dwell very deep in the ground or where fiercely malevolent creatures make plans to wreak destruction upon the surface world. Another form consists of secret rooms and chambers beneath vast citadels and fortresses, where even the owners of such places remain certain of what spaces exist "down there," built by some mad ancestor generations ago.
