The two came to blows, fighting each other to a standstill. Arriving in the structure's depths, he found his fellow angels dead, and Diablo, Lord of Terror, waiting for him. Tyrael urged caution, but Imperius ignored him and entered the fortress himself. Imperius sent the Heavenly Host after them. Imperius bested a gigantic one-eyed demon by himself, and the demons retreated to their fortress. On one such battlefield, Imperius and all four other Angiris Council members took the fight to their demonic foes.

By Imperius's own account, he and Tyrael saved each other's life on the battlefield countless times.

It is written that in one of Imperius's invasions of Hell, Solarion (his spear, forged by Imperius in the heart of a dying star) felled so many demons that rivers of blood flowed throughout the seven realms of the Great Evils. When Hell's legions lay siege to the High Heavens, it was Imperius who rallied his fellow angels to action, always the first to storm out of the Diamond Gates and charge headlong into the scattering armies of Hell. When the war turned in Heaven's favor he was always the first to spearhead the most daring assaults into the Burning Hells. Over the aeons of the Great Conflict, Imperius trod where other angels dared not. Alongside Malthael, Tyrael, Auriel, and Itherael, Imperius formed the Angiris Council to lead angelkind. He was among the archangels, and among the five who best represented the five virtues of Anu (in his case, valor).
