Bruna was born on Dread Mountain and lived there with the rest of the Kin. However, one day the Dread Gnomes who also inhabited the mountain began to coat their arrows in poison from the Ooze Toad Gellick. This venom worked fast and killed hundreds of Kin in the initial attack. Bruna was one of the few who survived and fled to the winter home for the Kin, the Dreaming Spring, where she lived alongside other survivors and used the water from the spring to visit the mountain in her dreams. However, the Kin could not survive at the spring because they needed the cones of the Boolong trees to breed.
