Underdark (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Underdark is a fictional setting which has appeared in Dungeons & Dragons role-playing campaigns and Dungeons & Dragons-based fiction books, including the Legend of Drizzt series by R. A. Salvatore. It is described as a vast subterranean network of interconnected caverns and tunnels, stretching beneath entire continents and forming a literal underworld for whichever surface setting it is added to. The Underdark is featured prominently in the campaign settings World of Greyhawk and the Forgotten Realms. The concept of a dungeon that spanned a planet was first introduced by Gary Gygax in his D-series of game modules and at the end of the G-series. The Underdark is described in detail in the 1986 manual Dungeoneer's Survival Guide, by Doug Niles. It is also a part of the Eberron campaign setting, in which it is called Khyber and is home to a host of evil beings driven deep into the caverns at the end of the age of demons.
