Once an assassin for hire, a sorcerer only in name, exiled from the Dragon School of Vinheim after turning Undead, on a journey to explore the depths of sorcery.
Once Orbeck has relocated to Firelink Shrine, he will ask the player to bring scrolls as a deal for him to stay. If the player defeats any four bosses before bringing Orbeck a scroll, he will hold true to his promise and depart for the rest of the game.
If Orbeck has been recruited, Yuria of Londor will tell the player in dialogue to "deal with him" in reference to Orbeck. The player can either kill Orbeck and loot his ashes or wait until he leaves to the Grand Archives and loot them from his body there. Either way, give the ashes to Yuria to receive the Morion Blade.
