General Description[]
Physical Description[]
From Even the Wingless:
He was black from tip to toe with the largest crown of horns Lisinthir had seen; and he'd seen several score males while walking down the long carpet to the front of the Emperor's court perch. Every move the male made was pregnant with menace and power, and his eyes when he turned them on Lisinthir were not merely yellow, but fluorescent, cannily intelligent, wickedly amused.
