Lurkers in the Dark

From publisher blurb:

Dwell in Darkness

Monster Menagerie: Lurkers in the Dark sheds light on whole new worlds of the Dark Folk. Within its dimmed pages you will find:

New races of dark folk, including the dark dweomerthief, dark piper, dark reeker, dark regent, and dark tatterdemalion.
The dark hound, an eerily quiet canine companion to many who dwell in sunless lands.
Dark folk history, alchemical items, and poison.
Notes for a sample dark folk in a cave system hidden beneath the waterfall of a subterranean river.
Player-friendly material for dark folk characters, including a dark folk player character race, archetypes, and feats.

Shun the light.
