Nurah Dendiwhar

Nurah is a historian and expert on the region of the world previously known as Sarkoris, and now known as the Worldwound. Having served in the Fourth Crusade, she at an unknown point switched sides and joined the demonic forces. A saboteur and spy, she was seen by one of the Heroes of Kenabres putting the highly addictive, and dangerous, drug known as Shadowblood into the backpack of Aron Kir, in an attempt to have him relapse into addiction. She was finally outed when discovered trying to sabotage siege ladders during the Assault on Drezen, and had to flee the camp towards the Citadel of Drezen.

If one were to succeed in turning her back towards the light, and purging the corruption in her soul, her knowledge would still be incredibly valuable in the region.
