Lord Asmoth Neth'khadar

The Daemon Prince general of my Chaos army. Neth'khadar (which when translated from the Dark Tongue means "Lord of the Night") is not only a fierce warrior but a mighty sorcerer, commanding magical flames with but a whim. His hold on the material realm is especially strong, making him very resilient to the attacks of his foes. Neth'khadar is blessed with the Mark of Chaos Undivided, as he worships the Chaos Gods as one all-powerful entity. It is his reputation for spreading terror into the hearts of all that hear his name that gave his army its title of "The Nightmare".

"You can never slay me. I live forever in your nightmares"
