Pontiff Sulyvahn

Pontiff Sulyvahn is a boss character in the video game Dark Souls III.

Biography
In his younger days as a sorcerer, Sulyvahn discovered the undying flame of the ancient Profaned Capital. The flame gave Sulyvahn a newfound ambition to conquer the Boreal Valley, which the Profaned Flame was situated under, taking upon a greatsword bearing a flame similar to the Profaned Flame's. Upon fulfilling his goal, he formed his Outrider Knights to enforce his rule, even forcing his compeers to wear a ring that, should they ever question his ideals, would drive them mad with visions of battle unending and send them afar from the Boreal Valley in said madness.

Sulyvahn would eventually institute worship of Aldritch, Saint of the Deep and a Devourer of Gods, into the city of Irithyll, taking the title of Pontiff upon it's formation. The Church of the Deep would regularly grant Aldritch sacrifices, to sate his insatiable hunger. Sulyvahn decided to further his grip over the Boreal Valley and sent Aldritch to devour Gwyndolin, the last of the gods in the old Anor Londo.
