"If I want to murder the stars, I'll murder the shit out of them! And you don't get to criticize me over that! FUCK THE STARS! THEY'RE TOO BRIGHT, YOU HEAR ME?!"Ahzek Ahriman is the First Captain of the Thousand Sons and a Champion of Tzeentch.
Official Canon Edit
After the Horus Heresy, Ahriman attempted to save his fellow Thousand Sons from crippling mutations by casting a spell called the Rubric of Ahriman. While it did stop the mutations, any non-psychic brother was now permanently turned to dust trapped in their armor. Enraged, Magnus cast Ahriman out from the Thousand Sons.
Since then, Ahriman has been attempting to enter the Black Library to gain the power that he believes will allow him to ascend to godhood and undo the tragedy that befell Prospero. He will stop at nothing, including torture and murder of countless people and backstabbing allies.
TTS Canon Edit
Ahriman succeeded in locating the Black Library, but before he could enter, he was blocked by Cegorach, who proceeded to ridicule and toy with him before kicking him out. Upset with the setback, Ahriman decided to go on vacation. However, his invitation was interrupted by a summons from Abbadon to join the new Black Crusade.
He has a strange fixation with "murdering the stars."
Ahriman ran into Lucius the Eternal, who wanted to spread the word of Slaaneshmas. Thinking that it would be amusing, the two of them joined up with Fabius Bile to create a special broadcast that would be aired on every station in the Imperium.
