This is the same character as Dragonslayer Ornstein from the previous games. He left the ruined cathedral of Anor Londo to search the Nameless King. After reaching Archdragon Peak, he evidently discarded his armor and weapon in the same area where the Nameless King is encountered. It is speculated that Ornstein joined the Path of the Dragon covenant and possibly transformed into one of the many Dragon Men locked in prayer in the area. It has also been speculated that Ornstein may be the wyvern upon which the Nameless King rides during the first stage of the battle.
