An Elenorian with a strong desire to escape the rather structured and stuffy culture in the Forest, Persidium turned to crime and hit the road. Falling in with Malaras and the other folk concerned with the Zenarth stone, he became involved in the quest, stealing from pretty nearly everyone he met on the way except his fellows in the party.
Shortly after that, the party were confronted by Queen Illyanth herself, who demanded the gem haughtily. This sort of thing was exactly why Persidium had left Elenoria in the first place, and it infuriated him. Once the Queen turned her back, he attempted a backstab, muffed it, and was promptly beheaded.
