Otterheart was a lone wold scavenging her way across the Deciduous Forest. Glacierstar found her alone and offered her a position in the pack. She greatly accepted the spot and found herself fitting right in with her charming attitude. She became a chaser for the pack and worked her way to deputy through Stormstar.
Blizzardstrike mated with her after a few months of being apart of the pack. It was his last breeding, and he unfortunately did not get the chance to meet his pups. Otterheart had three pups, however only one of them seemed to be strong enough to keep surviving which was Coalpup.
