Derro High SavantCreature

Derro are a degenerate race of dwarven stature. They have been skulking in the Underdark for ages, but they were discovered by the mind flayers only five centuries ago, and by the drow shortly before that. The derro have made a name for themselves by their marked cruelty. It is said that a derro lives for just two things; to witness the slow, humiliating death of surface demi-humans, and especially humans; and the perversion of knowledge to their own dark ends.
