The Fifth Battle of the Diamond Gates was one of the few times the Prime Evils truly worked together, and their combined might almost felled the gates leading to Heaven itself. Just when it seemed the Prime Evils would win the Great Conflict, Diablo turned on his fellow Evils, determined to be the sole ruler of both Heaven and Hell. The attack was halted as the forces of Hell battled each other, and Izual rushed to the defense of the gate, beating back the Evils and their hordes with his angelic runeblade Azurewrath, and valiantly saving the Diamond Gates, and Heaven.
