Ormus is one of the main vendors and healer in Act III of Diablo II. He talks to the player in an often cryptic manner, speaks of himself in the third person, and claims that he was once a Great Mage. Ormus belonged to the Taan Clan and was a follower of Skatsim the old religion of Kehjistan before the advent of Zakarum. Apparently, Natalya is present in the Kurast Docktown because of Ormus' presence there. Ormus gives you the Blackened Temple The Guardian quests, and also finishes the Blade of the Old Religion quest.
