Derro

"A small, stocky dwarflike creature in studded leather armor titters and mumbles to himself. His skin is a pale blue-white color, and his bulbous white eyes have no irises or pupils. His hair is coarse and white, and a long mustache droops past his chin."

Derro were a species of monstrous humanoids that inhabited the Underdark.

Physical description
Derro appeared to be some degenerate hybrid of dwarves and humans. Their rough skin was white with blue undertones and had sporadic tufts of coarse tan or pale blond hair. The eyes of the derro lacked any visible pupils.

Derro were degenerate and evil creatures of the underground, created from dwarf and human stock by some nameless deity of darkness and madness. Incredibly cruel and murderously insane, they enjoyed taking slaves and torturing surface dwellers (especially humans) to death.

Derro were afflicted by a form of racial madness, which most often manifested as delusions of grandeur coupled with an overpowering urge to inflict torment on other creatures. Derro were capable of holding their murderous impulses in check for short periods of time in order to cooperate with creatures of other races, but such arrangements rarely lasted more than a few weeks. Of course, no derro was capable of recognizing that he was out of his mind.

Combat
Derro were stealthy and bloodthirsty. They liked to carefully arrange cruel traps and deadly ambushes, and struck savagely from hiding. They delighted in taking captives who could be tortured to death later, and favored traps and poisons that disabled without killing.

Society
Derro were widespread and were likely to be found in small bands throughout the Underdark. Derro warrens existed in many drow and duergar cities; independent derro strongholds lay in the deepest reaches of the Underdark. Derro scouts and marauders searched the areas around their settlements for victims to enslave and torment.

The derro were a strange and sadistic race. While clever and stealthy they were also murderously insane. It was very common for derro to devote themselves to some strange quest, such as collecting only certain types of gemstones or slaying as many members of a particular race as possible. Some derro were assigned specific missions by powerful derro savants, with the possibility that they might even join a company of comrades to fulfill some irrational goal.

Religion
Most derro revered the god Diirinka, but very few became actual clerics.

Derro characters
Most derro revered Diirinka, a chaotic deity of magic and cruelty. Very few derro were clerics, but those who followed this path could choose two of the following domains: Chaos, Destruction, Evil, or Trickery.


 * The leaders of the derro were spellcasters called savants, whom other derro followed fanatically. Derro savants were at least 5th level sorcerers; they had one to three Knowledge skills (usually arcana and other esoteric fields). A savant was accompanied by two lower-level students. Savants used their spells to confuse and frustrate rather than kill, preferring to make slaves of defeated foes.

Origins
Legend has it that the derro originally lived on the surface of Faerûn. They opened portals to the Far Realm which offended the World Serpent who cast the derro into the Underdark.
