Eyghon the Sleepwalker was an ancient possessing demon know at least since the times of the Etruscan civilization, where Eyghon's initiates tattooed themselves with his Mark in order to summon the demon. At some point the group lost control of Eyghon and the demon took permanent possession of Randall. The rest tried to exorcise Eyghon but only succeeded in killing Randall. Afterwards, the group broke down and each went their way. However, Eyghon swore to kill the rest for toying with him.
