Codex/Story of Hell

Hell Barges
Atop mighty Thralls, the Hell Priests oversaw the invasion of the mortal world. The Thrall, slave titan of the underworld, carried the Priest Temples into the wake of battle, providing the Priests with vigil of Hell's advance from a strategically impervious emplacement. From their Temples perch the Priests would emanate a powerful psionic influence, imposing greater coordination among the chaotic forces of Hell and increasing their battle effectiveness. The Thrall, possessing superior resilience, proved indestructible by conventional weapons, thwarting all attempts by ARC defensive forces. Only by severing the Priest's psychokinetic tether could the Titan be neutralized - an act that could only be accomplished by an infiltration of the Temple itself.

Hell Priests
Powerful practitioners of arcane magics, the Priests have warped their powers to suit their insidious purpose, harnessing the dark forces of Hellish psychomancy to prepare Earth for the final Blood Ritual. By blood were the Hell Priests bound to the dark ritual which now consumed Earth, and so long as even of them lives, the consumption of Earth would continue, allowing Hell unfettered rule of the mortal world. Only by destroying the priests can the Blood Ritual be stopped and the Earth saved.

Deag Nilox
One of the three Hell Priests, Deag Nilox is charged with ensuring that Hell's invasion of Earth succeeds. He prefers to operate on the planet's surface, working in his unholy barge carried on the back of a demonic titan. This provides him an elevated, mobile position with which to oversee the campaign against humanity. Spiteful and cruel, Nilox frequently captures civilians alive so that their still-living blood can be harvested for his occult rituals.

Doom Hunter
Once a race of beast-like hunters, the Doom Hunter creature was known to Sentinel warriors in ages past as lethal stalkers of the Metal Age. Extracted from the frozen depths of the polar tundra, the Doom Hunter belongs to an ancient race uncovered during Cultist excavation in the remote arctic. Preserved below the frozen ice for millions of years, the unearthed remains of this creature were deemed suitable for reconstruction, becoming the subject of Cultist necro-regenerative bio-experimentation. Within the remote Cultist citadel, a high-tech ritual altar which towers over the Golgothan ruins, the Doom Hunter was ceremoniously and systematically resurrected and rebuilt. While the majority of its components are now cybernetic it retains a high degree of mental faculty - a sentient, brutal hunting instinct augmented with the armaments of a tank division.
