Kozzak is an asura of the College of Statics and a member of Pokka's krewe, which is the krewe of asura player characters who choose that college. Pokka's krewe brings their Very Old Energy Detector (V.O.E.D. for short) to the Snaff Prize, where they dig up nearby magical artifacts, including the head to a statue of Kormir and a raptor egg that hatches. Kozzak names the baby raptor, which he finds adorable, Shrieksy and keeps it as a pet which accompanies him in all later interactions.
Later he is acting as scribe for his krewe leader's achievements during the Cathedral of Silence mission. While overall helpful, being in the Temple of Grenth makes him extremely uneasy and he frightens easily.
