Rank 2: Nagash
Nagash’s influence on the Old World is hard to overstate: He is the first necromancer, lord of all vampires and other undead – the personification of death. His actions led to the destruction of Nehekhara (a civilization inspired by ancient Egypt) and the rise of the Tomb Kings.
Nagash returns with the “Lords of the End Times” DLC for Total War: Warhammer 3:
Through contact with Warpstone, Nagash became a lich and left behind his human form until he was just a large, flaming skeleton. Since then, the necromancer has repeatedly died – but always returned to conquer the world.
In the End Times, Nagash was brought back by Arkhan the Black and Mannfred von Carstein. There he also became an avatar of one of the winds of magic, specifically Shyish – the wind of death. Nagash gathered the undead rulers (except for Settra, for Settra serves no one). He made his most loyal into his Mortarchs – including Arkhan and Mannfred.
Nagash was never a servant of the Chaos Gods; he saw himself as their rival. From his black pyramid, he waited for the right moment to confront them in battle – a moment that, however, did not come before the world perished. Perhaps the Old World could have survived if Nagash had allied with the “Good” – whether life under the necromancer would have been much better is another question.
