From publisher blurb:
Stare Into the Void!Staring into the void, the derro are waiting in their twisted cities to oversee the descent of the world into insanity and destruction. But a few of them seek a wider realm...
The strange little derro are an unlikely choice for player characters (and this supplement provides much fuel for NPC anti-paladins and savants!), but they can be a wonderful change of pace in any underdark campaign or any game with a wide scope.
Advanced Races: Derro gives you everything you need to play one of these subterranean dwarves who has seen too much, starting with derro PCs abilities, culture, quirks, and richly expanded Pathfinder RPG rules. This 19-page sourcebook includes:
