Once a lone survivor of a remote northern expedition decimated by a Wendigo, he dedicated years to studying and hunting the creature across frozen wastelands until successfully killing it. His expertise caught the attention of Ixchel, who recruited him to apply his unique tracking methods to the Chupacabra hunt, recognizing that knowledge of one apex cryptid predator could prove invaluable against another.

The Wendigo Sentinel possesses an uncanny ability to sense supernatural entities, a skill developed during his years tracking the Wendigo through blinding blizzards and sensory-depriving conditions. He carries specialized tools adapted from northern hunting techniques, including scent-masking compounds and sound-dampening equipment that work equally well in dense jungle foliage. Years of exposure to the Wendigo's influence has left him partially immune to the fear-inducing auras that cryptids often project, allowing him to maintain clarity when others might panic.

Within the Shadowmane Hunters, he serves as both an early warning system and elite tracker, often ranging far ahead of the main group to detect signs of the Chupacabra that others would miss. His comparative analysis of cryptid behavior patterns has provided the faction with critical insights into predicting the Chupacabra's movements and potential weaknesses.
