Descend Into The Darkest Reaches of the Realms
The ebon depths of the Underdark have spawned more fables and fears than any other region of Faerûn.

Explore the labyrinthine tunnels and endless caverns of the Realms Below to encounter the denizens and dangers of one of the most intriguing, inhospitable regions in the Forgotten Realms game setting.
