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 are a species of monstrous humanoids that inhabit the Underdark.

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

Derro are 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 enjoy taking slaves and torturing surface dwellers (especially humans) to death.

Derro are afflicted by a form of racial madness, which most often manifests as delusions of grandeur coupled with an overpowering urge to inflict torment on other creatures. Derro are 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 last more than a few weeks. Of course, no derro is capable of recognizing that he is out of his mind.

Combat
Derro are stealthy and bloodthirsty. They like to carefully arrange cruel traps and deadly ambushes, and strike savagely from hiding. They delight in taking captives who can be tortured to death later, and favor traps and poisons that disable without killing.

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

The derro are a strange and sadistic race. While clever and stealthy they are also murderously insane. It is 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 are 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 revere the god Diirinka, but very few become actual clerics.

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


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