Thelion is the founder and leader of a resistance group called The White Thorns who are stationed in the Iron Hills and are dedicated to overthrowing Lord Soth. She despises Lord Soth for sending Azrael Drak to murder her family when she was a child. She has recently tasked the party with retrieving her family sword, The Nightblade, from the armory at Nerdragaard Keep and with recovering The Chasm Crawler at Sumpfberg so that the White Thorns can attempt to destroy or neutralize the dragon Cthonyx.
