Underdark

The Underdark, a fictional region, is the vast network of underground caverns and tunnels underneath the continent of Faerûn in the Forgotten Realms setting of Dungeons & Dragons roleplaying game.

The Underdark is extremely dangerous, especially to those not native to it. There are the usual dangers associated with caverns: claustrophobia and getting lost. There is no light; most Underdark inhabitants either have highly developed senses other than sight or have developed infravision.

In addition to those dangers, the Underdark also is the home of many predators and hostile races, including:


 * drow (dark elves)
 * mind-flayers
