In life Chauch-eta was a female half-orc. In death, she was raised as a skeletal mage under the Scourge. This creature might have once been a half-orc, though now it is barely more than a skeleton. Silvery, translucent skin stretches tight over its form, accentuating its skeletal frame.
She retained all of her intelligence and memories before her transformation into undead, and she also has an intimate connection with the minds and senses of all the undead under her command.
She may know things that her undead minions have discovered, even if the minion was not intelligent to make sense of its findings. She knows several languages (Abyssal, Common, Gnoll, Orcish, and Undercommon).
