Derro

Derro are a degenerate race of dwarven stature. They have been skulking in the UnderWorld for ages, and 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 demihumans, and especially humans; and the perversion of knowledge to their own dark ends.

Derro are short, with skin the color of an iced over lake (white, with bluish undertones), sickly, pale yellow or tan hair (always straight), and staring eyes that have no pupils. Their features remind dwarves of humans, and vice versa. Derro have rough skin, spotted with short coarse tufts of hair. Most derro wear a loose costume woven from the hair of underground creatures and dyed deep red or brown. Their armor is leather, studded in copper and brass. Leaders wear tougher, kather armors, made from the hides of beasts far more rugged than cattle.

Note: Derro originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
