Heading the tribe of Icewalkers infected with lycanthropy in the Cragmaw Heights, Jominn was a fierce warrior and very protective of her people's ways and protection. She encountered The Party and thought they were allied with Folduin Caerlinn at first, but quickly found out that they opposed him, after which she offered a bite of food and shelter in the tribes quarters nearby.
Jominn had a burning hatred for The Farwalkers, as she was cast out from Farhold along with her kin for refusing to adhere to the ways of the cult. She also wanted to slay Folduin Caerlinn, just like he slayed her brother in cold blood in front of her and her tribe.
