A Gnome wizard with a gift for summoning spells, Marius is currently a fighter in the arena in Safaga. He is being sought by Baz as his new main event in Cothrom. Unfortunately, he has gotten himself in trouble with the Silent Strike, the Yuan-Ti crime family that runs the arena.
The party negotiates his release from indentured servitude to the Silent Strike in Session 19 and brings him back to Cothrom to join Baz's arena.
