Sathariel

Sathariel was a dark angel in the service of the evil deity Asmodeus. His exact nature is unknown and, although he was described as a dark angel, he may in fact have been a devil. Alternatively, he could have been a fallen angel.

Sathariel lived in Waterdeep and oversaw the operations of the Vigilent Order. In 1480 DR, he attempted to complete the ritual of the First Flensing, a spell that would have opened a gate to the Prime Material Plane for Asmodeus' use. He was slain by the deva Jinnaoth Ir'Gadohn in 1480.

He had silver armor and wielded a silver sword.

Appearance
Sathariel had black feathers on his wings and his body was shrouded in darkness.
