Umbra

Umbra was the leader of the Dragonbloods, a Luskan gang. He was rumored to be a dragon but he was actually some sort of doppelganger. Umbra's face constantly shifted and his true form was unknown.

In 1480 DR, while investigating the Fury plague sweeping Luskan, Myrin Darkdance and Kalen Dren visited Umbra at the Dragonblood's compound. Umbra had been Myrin's lover many decades ago and when he kissed Myrin she absorbed his memories of her. Unfortunately, while absorbing Umbra's memories, she inadvertently drained his life force, leaving him a pile of dust.
