Dark Sun: The Scorched World of Athas
Skull of Dorag Thel
This artifact is a human skull, browned with age. The teeth are chips of obsidian, and each eye socket contains a large emerald. A living vine snakes its way through the skull. Although the skull appears weathered and fragile, it is indestructible.
The skull is all that remains of Dorag Thel, an ancient druid of Athas from the days before the world became a wasteland. Dorag warned about the adverse effects of defiler magic, but to no avail.
The skull was lost for many years but reappeared in the hands of Abalach-Re who used it to help further her transformation into a dragon queen. After her transformation was complete the skull was collected by Li-Am before he and his allies fled.
Following the treachery and death of Li-Am, the Skull was retrieved by Elleandra.
