The Old Gods were the original pantheon of the planet Zakuul, consisting of six primary gods. Izax, the Ultimate Devourer, was the chief deity of the pantheon, while the other members were his wife, Scyva, and their four children: Tyth, Aivela, Esne, and Nahut. The demon serpent Zildrog was another entity worshiped by the Old Ways, though Zildrog was often considered simply an aspect of Izax. Valkorion claimed to be the Demon Savior of prophecy, one who would topple the Old Gods and usher in a new era of prosperity, and worship of the Old Gods was mostly abandoned by his Eternal Empire. The Heralds of Zildrog still followed the old ways but were considered more of a cult.
