Qho'shrain

Qho'shrain is a Daemon of Slaanesh, currently possessing the body of Sebastian Creit. Qho'shrain is bound to the will of the Exarch of Pleasure, Amet Volupte, due to a daemonic pact. Qho'shrain is often quick to violence, and even quicker when acting it out, slicing through hordes of people with its claws and ripping them apart with pure warp energy

History
Originally known as Sebastian Creit, his almost lifeless body was possessed by a relatively powerful Slaaneshi daemon after his ritual was assaulted by the Argent Leviathans during the Coroxian Crusade. After the Space Marines had left, the daemon that called itself Qho'shrain changed his form brutally to fit its own demands. When this was completed, Qho'shrain was able to make their way through the warp onto Coroxia Prime as the Argent Leviathans assaulted it. From here, it assisted in the defense but left with the rest as the Argent Leviathans took too much ground.

Qho'shrain itself is bound to the will of the Exarch of Pleasure, so it cannot betray him or disobey his orders. Volupte sees Qho'shrain as a pawn to be used, but it is extremely effective at most things that he requires it for. Qho'shrain is capable of telepathic speech, as its mouth is only capable of producing mainly incoherent screeches. It sees itself as above mortals and tends to send most of the Arm Diablos' forces as a first wave to break the enemy's defenses, with no concern to the loss of life.
