Editing Arkhan the Black (section)

===Vizier of Khemri===
When Nagash sought a cabal of followers to assist him in usurping the throne of Khemri he found them in Arkhan and his compatriots. They were convinced by a demonstration of Nagash's newly created art of necromancy, and first supported Nagash by kidnapping victims off the streets to both supply Nagash with test subjects and undermine his brother’s rule. Arkhan and the others started to learn rudiments of necromancy themselves during this time, and he was the first of Nagash's followers to partake of Nagash's elixir, becoming the first of Nagash’s so-called "Immortals".

When Nagash finally usurped his brother’s throne, declaring himself king of Khemri, Arkhan was appointed his vizier. Arkhan carried out Nagash's orders with a loyalty and alacrity he'd never shown before due to Nagash giving Arkhan everything he wanted and relying on Nagash for more of the elixir. This tyrannical regime led the Priest Kings of Nehekhara to form an alliance against Nagash, and Arkhan served as the great necromancer's foremost lieutenant in the struggle that followed, putting his newfound necromantic talents to use helping maintain Nagash's undead armies. Battle after battle was waged, but inevitably the more numerous forces of the Priest Kings proved too much, and Nagash and his armies were forced back into the city of Khemri.

In the battle for Khemri, Arkhan led the suicidal counterattack that allowed Nagash to escape the Army of the Seven Kings, single-handedly holding off his foes with spell-casting and swordplay for an hour before he fell. There are different acounts of Arkhan's defeat across the editions of Warhammer:
* Some random schmo managed to hit Arkhan in the heart with a thrown spear and Arkhan died, his body consumed by black flames and leaving behind a skeleton. While the Nehekharans destroyed the bodies of Nagash's other followers, they didn't desecrate Arkhan's remains out of respect for his badass last stand and simply built a stone cairn over them (first version).
* Same as before, except instead of respect for his last stand they didn't desecrate Arkhan's body because Arkhan gave a curse with his dying breath that anyone who touched his bones would die horribly (second version).
* Lamashizzar snuck up on Arkhan, carrying a prototype Cathayan gun. He used this to shoot Arkhan in the heart and incapacitate him for transport to Lahmia. The "spear thrown into the heart by an unknown soldier" was a cover story made up by Lamashizzar (most recent version, and canon as of the End Times).
