Izax, the Ultimate Devourer, also known as the God of Death, was a god venerated by the inhabitants of Zakuul in the era preceding Emperor Valkorion's ascent to authority and the establishment of his Eternal Empire. He held the position of primary divinity within the Zakuulan pantheon, and was married to Scyva and fathered Tyth, Aivela, Esne, and Nahut.
Izax's origins trace back to an experimental titanic wardroid superweapon from Iokath, crafted by an ancient, yet technologically superior, civilization. He, together with his five siblings, underwent trials on multiple unsuspecting planets, resulting in more than ten trillion deaths, with Zakuul being one such world, explaining Izax's deification there.
He was defeated in combat by a specialized team, including the Outlander, Scyva, and various other participants.
In one of Vaylin's propaganda addresses, she scornfully labeled Zakuulan insurgents as those "who desecrate Izax."
