The Nameless King

The Nameless King was a dragon-slaying god of war in the Age of the Gods and heir to lightning, until he sacrificed everything to ally with the ancient dragons. He tamed a Stormdrake and formed a close bond with it, leading it to countless battles. He is a former king. However, it is not known which kingdom he was the king of. Dragonslayer Ornstein, another relic of the Age of Gods, left the ruined cathedral Anor Londo he once guarded in search of the Nameless King. It is heavily implied that the Nameless King is the long-speculated firstborn child of Gwyn, Lord of Sunlight.
