A loner for many months, and hesitant to talk about her past, Tumble is a modest and timid wolf with skills in foraging and herb-mixing. Unique among the Sisters of Selene as abstinent from meat-eating, she has managed to acquire a knack for identifying and preparing a number of mountain-local berries, fruits, nuts, and other plant parts - as well as the well-honed ability to snatch eggs from other creatures.
Tumble was present at a meeting between the Sisters and the Pack of Rabbits headed by the forest wolf Jusinet. She was a part of the leaders' negotiations regarding necessary mange medicine for the wolf Earthsky - in exchange for her medicine, she was bred by their stud Naisn.
