Deck of Many Things 4th Edition
Araliss is a strange young Eladrin who previously ran a small gang out of an unknown town the party visited. His party members and pet Rage Drake were killed by the adventurers. He was also thought dead, however he managed to escape while the adventurers dealt with the rest of his party. Araliss escaped into the forest, where he met with a strange Shadar-Kai woman. He paid her off with one of the missing cards from the Deck of Many Things and a sample of his blood to complete a demonic summoning ritual that she was in the process of casting. Once he paid her off, he escaped into the forest before the party could follow.
Araliss encountered the party again inside of a nearby castle. He told them that he was being employed by someone to do the things he has done thus far, and began to tell them exactly who. He also was moments from handing the party a stack of cards missing from the Deck of Many Things. However, before he could accomplish the task, he was killed by a mysterious man in black, who summoned undead to distract the party while he escaped.
