<blockquote>"The greatest of these heroes was Izual, lieutenant to the Arch-Angel [[Tyrael]] and bearer of the Angelic Runeblade [[Azurewrath]]. He once led a fierce attack upon the [[Hellforge]] as the creation of the dark demonblade [[Shadowfang]] was nearing completion. His quest was to destroy both wielder and weapon- a charge that he was destined never to complete. Izual was overcome by the legions of chaos and, tragically, was lost to the Darkness. His fate stands as testament to the fact that Angels and Demons alike shall fearlessly enter into any domain - so long as their hated enemies dwell within."</blockquote>

Most histories of the [[Great Conflict]] like the above describe Izual as a misguided martyr-hero. Even Tyrael always believed his most trusted Lieutenant was a brave fool. However, it is revealed in Act IV of Diablo II that Izual did not succumb to hubris, but rather joined with the {{iw|Prime_Evils Prime Evils}} in plotting their own exile on Sanctuary - {{iw|Dark_Exile Dark Exile}}. In his speech during Act IV, Izual said that their plan could "not be stopped by any mortal agency", and since the player fails to stop [[Baal]] corrupting the {{iw|Worldstone Worldstone}} later it is not certain whether that plan was foiled. However, it was clear from his twisted appearance and the fact he had lost the angelic blade Azurewrath that not everything had gone well even before Izual's death, so his speech could have been bravado.
