Ahsis was the Sunhawk of the Hunters Lodge in Horizon Zero Dawn at the time Aloy was trying to join as a Thrush. He did not make it easy for her, as he was very prejudiced and an elitist, viewing her as little more than a savage.
Ahsis become Sunhawk in the thirteenth year of Sun-King Jiran's reign after defeating a Thunderjaw that was ravaging Morning Light. Using its own cannons against it, he was the first to bring a Thunderjaw trophy to the Lodge, promoting him from a Hawk to Sunhawk.
He died while hunting Redmaw, an extremely ferocious Thunderjaw, in an attempt to prevent Talanah from usurping him as Sunhawk. During this hunt he also hired mercenaries to block Talanah's way, and went alone due to his vanity, not wanting to share the credit with his Thrush. Ahsis was violently thrown into the side of a ridge by a lash of Redmaw's tail, crushing his internal organs and causing "evidence of bowel failure". Before dying, Ahsis was still defiant of Talanah and Aloy, regretting that he hadn't sent them in first to soften Redmaw up.
Ahsis was a prejudiced and arrogant man, adamant about maintaining the traditions of the Lodge despite Avad's reforms.
- The Thunderjaw carcass on display in the Hunters Lodge is the same one that Ahsis took down to become Sunhawk.
