Aspen is a vulgar wolf who's loud and highly opinionated, but beneath that is the heart of a good animal who has a deep compassion for all living things.
Aspen was an orphaned pup when he joined PineFleet's pack. Dunley Bear found him in the bottom of a ravine in an abandoned nest. Whether it was intentional or not, It seemed that he'd been left behind. From then on Aspen has always viewed Dunley as a father figure, and sticks to him like glue when he comes home after every hunting mission.
Despite being so loud and rambunctious, LakeRunner gets along with Aspen incredibly well and the two are inseparable like brothers.
