Kholvaris is a lord of House Lucaris, and like all his kin he does not rule his god-machine alone. Bound within the frame of his ancient war-suit is a greater daemon of the warp, a bellowing entity that has shared his Throne Mechanicum for so many centuries that the two can no longer be told apart. Kholvaris speaks with the daemon's voice; the daemon rages with Kholvaris's cunning. Together they are the Hell-Baron, a thing of fire and spite that has led the Infernal processions of Lucaris out of the Eye of Terror times beyond counting.
Where Kholvaris treads, reality festers. His war-suit weeps boiling ichor and his weapons spit warp-flame that consumes body and soul alike. He revels in the desecration of holy things, and delights above all in corrupting the loyal Knights he once called kin, whispering to their machine-spirits until honour curdles into damnation. To the Imperium he is a monster without mercy; to House Lucaris he is a favoured champion, proof of the terrible power that awaits those who give themselves wholly to the Dark Gods.
