Diablo was gratified to sense the angel's fear. The Triune was nonetheless wiped out, and Diablo confronted Inarius directly. Diablo was interested in Uldyssian's might, especially in light of the demise of Gulag (a servant of Baal). Astrogha, Diablo's minion, reported to his master. In the last days of the Sin War, events were complicated with the emerge of the Edyrem, a group led by the nephalem Uldyssian who sought to end the influence of both the Triune and Cathedral of Light. He risks all that either of us would desire of Sanctuary!" This mortal, this Uldyssian, he has become more than any of us would imagine. There would have been nothing for me to devour if what you say is true. The Triune's efforts to ensnare humanity were hindered by the rogue angel Inarius however, who founded the Cathedral of Light. "Dialon" was said to bring purpose to humanity, and carried the "Tablets of Order." Each of the Primes took on an alter ego for worship and in Diablo's case, he was known as Dialon, the Spirit of Determination, represented by a ram in Triune iconography. To this end, they founded the Triune-a seemingly benevolent religion that was actually a front for their true motives. Sensing the dormant power within humanity and reasoning it could be turned to suit their own ends, the Prime Evils began a campaign to tip humanity over to their side. Diablo informed his brothers of this new world's existence.

Imperius responded that he feared nothing and continued fighting. They fought each other to a standstill as Diablo commented on Imperius's rage, and wondered aloud if his enemy (Imperius) feared of how the angels saw him for what he truly was. On one such battlefield, Diablo battled Imperius. Perhaps you fear them seeing you for what you truly are." With this discord in Hell's ranks, Heaven was able to drive the forces of Hell back. One example of these rare instances of cooperation was the Fifth Battle of the Diamond Gates, and just when it seemed that the Prime Evils would win the Great Conflict, they turned on each other, fighting over spoils that they had yet to win. However, the Prime Evils rarely worked together, though when they did, he served as the harbinger of their wrath. The Eternal ConflictĪs with all demons, Diablo partook in the Eternal Conflict. His domain in the Burning Hells was the Realm of Terror. Though he had easily possessed and corrupted many humans, Diablo's essence was finally trapped in a soulstone and banished to the unfathomable Abyss twenty years ago."Īs with all the Great Evils, Diablo spawned from one of the seven heads of the great dragon Tathamet.
