Al'Diabolos

Al'Diabolos, the Lord of Terror, more commonly known as Diablo, is the youngest of the three Prime Evils. As with all the Great Evils, Diablo spawned from one of the seven heads of the great dragon Tathamet. His domain in the Burning Hells was the Realm of Terror. He, Mephisto, and Baal were the three Prime Evils, and from the outset, warred amongst each other to maintain dominion and rule over the legions of the Burning Hells. Under Diablo's command, the Wrathborne solidified Diablo's rule in Hell. It is said that of the Three, Diablo is the most creative and farsighted of them, perhaps of all the Great Evils. He is calm, cunning, and patient. He sees himself as an artist of terror. He knows that conquest comes when enemies turn their back on fear rather than face them. However, Diablo does not acquire his satisfaction from conquest itself, as Mephisto might. Diablo feeds on the terror that precedes the conquest.
