Zanathakla

Zanathakla is an orium dragon who has made his home amidst some of the ruins in Estorium. He originally had a gang of lizardfolk gathering Estorian artifacts for him, but after the Challengers of the Unspeakable killed them, he took them Challengers themselves into his service instead. He was killed soon after by the wizard Theriana, who promptly raised him into undeath to serve her.
