When Rowan Oakwood sought to expand the Guardians' protective reach beyond the Pacific Northwest, ancient texts led to a secretive order of Filipino cryptid protectors who had preserved the Aswang's abilities for generations. After proving the Guardians' honorable intentions, the Filipino order sent one of their Aswangs to assist in protecting Sasquatch, bringing centuries of shapeshifting wisdom and night surveillance techniques to complement the Guardians' daytime operations.

The Aswang Attendant appears human during daylight hours but transforms into a hybrid creature at night, capable of silent flight and extraordinary stealth. Its enhanced senses can detect intruders miles away from Sasquatch territories, while its ability to communicate with nocturnal forest creatures creates an extensive warning network throughout the woods. The Aswang can mimic human voices with perfect accuracy, allowing it to misdirect Apex Hunters and other threats through disorienting calls that echo through the misty forest.

As the Wildwood Guardians' primary night operative, the Aswang Attendant maintains vigilance when human members rest, creating a continuous protection cycle for Sasquatch territories. Beyond its protective duties, the Aswang serves as a cultural ambassador, bringing Eastern cryptid protection techniques to the Pacific Northwest and helping establish a global cryptid defense network that shares knowledge across continents.
