Originally a spirit-guardian of the Arctic wastes, the Keelut was drawn to the Himalayas by the powerful mystical energies surrounding the Yeti's domain. Recognizing a kindred protector of sacred spaces, the Whiteout Guardians welcomed this supernatural being into their ranks, where it adapted its ice-spirit powers to serve as a sentinel of the mountain's most hallowed regions.

The Keelut Sentinel possesses the ability to merge with ice and snow, becoming virtually invisible in blizzard conditions. It can create disorienting snow patterns that confuse intruders and erase their tracks, while its supernatural tracking abilities allow it to follow those who have violated sacred spaces across any terrain. The creature's presence causes extreme cold that serves as a warning to those who venture too close to protected areas.

Serves as the Whiteout Guardians' primary boundary enforcer, maintaining a network of mystical barriers around sacred sites and ensuring that those who glimpse the Yeti cannot retrace their steps to its domain. Works in concert with other Guardian entities to maintain the veil of secrecy protecting the mountain's ancient mysteries.
