Warhammer - Time of Legends - The Rise of Nagash by Mike Lee

Nagash is the first necromancer and the supreme lord of undeath. He wrested the secrets of dark magic from the elves and perverted them to suit his ends. When the priest-kings of Nehekhara stood united against him, he broke their armies and sacked their cities. He raised the largest army of the dead the world has ever known and became an immortal dark god. His deeds are legend. This is his story.
