The Stardust Wraith, also referred to by Talmon as a samandarun, is an entity “from between the spheres” that hitched a ride on a githyanki ether ship and, in attempting to take control of the vessel, caused it to crash near the village of Dymon. Although spending most of its time in a host body, the wraith itself appeared to be made of glowing orange dust which was highly volatile. The slightest brush of fire caused it to burst into flames and disappear.
In its host body, the samandarun was able to burn people from inside with a gaze attack and appeared to have the ability to cast spells. Its capabilities in wraith form remain untested. Being possessed by the samandarun was lethal in the one observed case, leaving only a hollow corpse with charred bones behind.
