Also known as: 薪の王グウィン
Gwyn, Lord of Cinder is the main antagonist and final boss of the video game Dark Souls I.
He was once one of the wielders of the First Flame and one of the founders of the Age of Fire, but due to the aforementioned Flame dwindling over time, he sacrificed himself to preserve its lifespan, thus beginning the tradition of soul-sacrifice to extend the Age of Fire.
