Necromancers, called by a few as the Priests of Rathma, are a group that is commonly misunderstood and often feared by the common people due to their communication with the dead. According to the Books of Kalan, they were granted, by the legendary nephalem Rathma, the ability to bend the thin line between the life and death of mortals and they were asked to use it for a singular purpose: Keeping the balance between the Light and the Darkness and prevent both Heavens and the Hells to have power over the mortal world more than one another. The first mortal to follow Rathma’s teachings was Mendeln Ul-Diomed, who lived during the Sin Wars era. In time, he would be known as Kalan.
The number of Necromancers today is assumed to be around 150, mostly found to the east of Kehjistan. Their currently known leader is Deathspeaker Jurdann. The closest thing the Priests see to a deity is the ancient dragon Trag’Oul who protecs the balance. In addition to being able to commune with the dead, they have the powers to animate and control a dead body. While these powers are infamous as “dark” arts, their sense of pragmatism is so high that they are almost immune to temptations of corruption and power hunger that the Mage Clans were subjected to when they made deals with the demons.
Xul has a special place amongst the numerous Rathma Priests in the pages of history. Hailing from the southern swamps following Diablo’s possession of Prince Aidan and traveling to the east of Tristram, he went after the Dark Wanderer with a group of other heroes. Unable to stop Diablo neither from claiming his true form nor from meeting his dark brothers Baal and Mephisto, the heroes did free Archangel Tyrael from the Tomb of Tal’Rasha and defeated the Prime Evils by going through the portal in Kurast. Unfortunately, Baal, the Lord of Destruction, made it to Barbarian lands of Arreat, laid waste to Sescheron and managed the destruction of Worldstone. Against the advice of Deckard Cain, the last sage of Horadrim, the heroes returned to their former lives and homes. Xul’s life after this point is a mystery. The only piece of information about the Necromancer is that he took upon himself an apprentice named Mehtan and kept his struggle to keep balance.
If Xul’s disappearance is an effort to carry the balance to other realms, as rumors say, a piece of advise to everyone in Nexus: All who oppose him, beware!
