Derro

Derro resemble small dwarves. They have blue-gray skin, and their hair is often white, yellow, or a pale tan. They lack both irises and pupils, showing uniformly pale eyes. Most derro look haggard and wear shabby clothing, appearing pitiable to unsuspecting victims.

The duergar believe that the derro are another dwarf clan that was long held by mind flayers, which resulted in madness. The derro themselves all tell oft-changing variations of the myth of their god; all versions share a common focus on his stealing of magic from a great evil to help the derro survive through their ordeals of deceit and cruelty.
