Once a revered shaman in the remote mountains bordering Pakistan and Afghanistan, the Barmanou Mystic was drawn to the higher Himalayas after experiencing prophetic visions of the Yeti's sacred role in maintaining cosmic balance. After years of solitary meditation in ice caves where the boundaries between human and cryptid realms blur, he emerged transformed, possessing the ability to communicate with mountain spirits and was discovered by Tenzin Norgay, who recognized the ancient power dwelling within this half-human, half-cryptid entity.

The Barmanou Mystic possesses the unique ability to merge with mountain mists and snowfall, becoming nearly invisible when performing sacred rituals that confuse the senses of those who would track the Yeti. His body temperature can drop to near-freezing levels without harm, allowing him to survive in the harshest conditions while leaving no heat signature for modern tracking equipment to detect. He carries a staff adorned with ancient symbols that, when planted in snow, can summon disorienting whiteouts that protect sacred areas and erase all traces of the Yeti's passage, while his heightened senses can detect disturbances in the mountain's spiritual balance from miles away.

The Barmanou Mystic serves as the spiritual sentinel of the Whiteout Guardians, working closely with Tenzin Norgay to maintain a complex network of mystical barriers throughout the Himalayas that shield the Yeti's domain from intrusion while subtly influencing weather patterns and mountain conditions to guide worthy seekers toward enlightenment rather than exploitation.
