Originally from the coastal waters of Alaska, the Kushtaka Guardian sensed a disturbance in the balance between human and cryptid worlds when modern expeditions began pursuing the Yeti with technological equipment. Answering a mystical call that resonates between all ancient cryptid sanctuaries, it journeyed to the Himalayas where Tenzin Norgay recognized its dual-natured essence as crucial for protecting the boundaries between realms. The Kushtaka's traditional role as a gatekeeper between worlds made it uniquely qualified to become the Whiteout Guardians' specialist in maintaining the veil that separates the Yeti's domain from human intrusion.

The Kushtaka Guardian possesses the ability to shift seamlessly between human and otter forms, with its transformations becoming most powerful during twilight hours and near flowing water. In the Himalayas, it has adapted to the extreme cold, developing a thicker coat in its otter form and the ability to navigate beneath ice sheets for hours without surfacing. Its most mysterious power lies in its ability to extract specific memories from human minds, replacing clear recollections of sacred sites with dreamlike impressions that satisfy curiosity without revealing locations. The Kushtaka can also manipulate water in limited ways, creating misleading reflections or obscuring footprints in snow and ice.

The Kushtaka Guardian serves as the Whiteout Guardians' specialist in compassionate extraction and memory keeping, rescuing lost explorers who stray too close to the Yeti's domain while ensuring they retain only the wonder of their experience, not the specific knowledge that would allow them or others to return. It maintains the delicate balance between allowing humans to experience the mountain's mysteries and preserving the sacred boundaries that protect the Yeti's ancient wisdom.
