A slight, young man of around seventeen years, Auspicious Onyx Sepulchre is quite attractive in a solemn sort of way. He has pale skin, black hair, and the violet eyes of a Chosen of Endings.

Born to a family of ancient Sijanese thaumaturges tasked with maintaining the ancient tombs in Creation's greatest city of the dead, Onyx grew up surrounded by the trappings of death. He lacks most of the social graces useful in dealing with the living.
