Though generally assumed to be a dragon of the Drakar'ri, very little is known about the entity that is refered to as Xil'varath beyond rumour and speculation. Xil'varath is presumed to be a Drakar'ri entirely aligned with the Shadow, and one of the key elements behind the catastrophic event known as the Cataclysm. It is believed that Xil'varath was originally destroyed by Sara'tharalax, a Drakar'ri aligned with the Light shortly before, or perhaps soon after, the Cataclysm itself. The destruction is said to have been mutual.
