Acarithious

Acarithious Goreborn was a Chaos Lord of Khorne who was part of the Ascension of Madness narrative campaign.

Description
Back Story 

It is said he was struck down and killed during a small raid on the 7th moon of Dowbin sept. His hunger for destruction was greater then most chaos raiders and because of this Khorne had given him an opportunity. In death he was no use to anyone, so the blood god bathed him in the crimson pool left by his slaughtered foes. Warp power surrounded him and as the powers of chaos fed into his soul he felt the power seeping into him as if he stood next to the skull throne himself. In an Explosion of Carnage and as the red mist cleared, you could only hear the raspy breath of the newly reborn and now Lord of chaos. With Malice in his tone he speaks, "I am Goreborne."
