|Title||Lord of Sin|
Azmodan, The Lord of Sin is one of the four Lesser Evils which make up the seven Great Evils. After the events of the Sin War, Azmodan, together with Belial, banished the Three to Sanctuary when they realized the Three were planning to break the pact Hell had made with Heaven. This began the time known as the Dark Exile. Shortly thereafter, a civil war broke out between the two Lesser Evils, which Azmodan quickly won. He has ruled Hell for the last 300 years to this day. He is also the ruler of the Realm of Sin in the Burning Hells.
During the Black Soulstone cinematic first revealed at Blizzcon 2011, it is revealed that it is Azmodan who is invading Sanctuary during the events of Diablo III. The reason is because he seeks the Black Soulstone, with which he intends to become "The Prime Evil".
 Pre-Dark Exile
Though not one of the three dominant heads of Tathamet, the ambitious Azmodan has long sought to claim supreme ruling power in the Burning Hells, and in his first attempt, one that ultimately failed, he used the Fallen Ones in an effort to dethrone the Three, but his machinations failed to suffice, and the Fallen Ones were twisted into small and feeble versions of themselves by Diablo, a condition the enraged Azmodan refused to reverse. Notably, however, the Fallen Ones's failure at least managed to provide Azmodan with the information to mastermind the successful Dark Exile.
 The Dark Exile
Azmodan took part in the Dark Exile overthrowing the Prime Evils, wrongfully believing Diablo and his brothers to have hesitated in the Great Conflict. During the Dark Exile, Azmodan ruled half of Hell, opposing Belial. It is not known whether Azmodan joined Andariel and Duriel in supporting the Prime Evils' return. This point is moot, however, as all three Prime Evils were slain before they could formally take power over Hell again. It is likely that Azmodan and Belial returned to their civil war after the Prime Evils were defeated. Shortly after, Azmodan won.
 Invasion of Sanctuary
You thought you were so clever, that you had outwitted us all. One by one, our brethren fell into your trap, but not me. I defy you! I now know the Black Soulstone is the key, and it shall be mine. Soon, my armies shall pour forth from the Shattered Mountain, ravaging this world and all hope of resistance. My minions will find the stone, wherever you choose to hide it. Then, at long last, Azmodan shall reign as the Prime Evil.
— Azmodan's parting words
After Belial's defeat at the hands of the nephalem heroes, Leah had a vision of Azmodan where he revealed that he intended to lead a full invasion of Sanctuary to find and claim the Black Soulstone with which he could become a fusion of all the Great Evils, the Prime Evil. The vision held true and Azmodan's armies poured forth from the Arreat Crater and laid siege to one of the last barbarian strongholds; Bastion's Keep.
His lieutenants, the Sin Lords, were introduced, with Ghom, the Lord of Gluttony, storming the depths of Bastion's Keep while the nephalem heroes rallied the stronghold's defenders and raised its catapaults. These same heroes destroyed Ghom and began to push Azmodan's forces back into the Mount Arreat crater and through the portal. Azmodan's consort, Cydaea the Mistress of Lust, tried to slow the nephalem as they fought through the portion of Hell just inside the crater and destroy the Sin Hearts, relics from the depths of Hell that empower the demons. Eventually Cydaea was slain as well and the Sin Hearts were destroyed.
At last the nephalem confronted Azmodan himself, who reiterated his desire to become the Prime Evil. His plan was ultimately left unfulfilled when Azmodan was defeated and his spirit was sealed within the Black Soulstone, making him the final of the Great Evils to be locked in the stone. Shortly afterwards one of Diablo's secret operatives revealed the Lord of Terror's own plan to become the Prime Evil had reached fruition and the Black Soulstone was bound to Leah Cain's body, through which Diablo manifested himself and proceeded to assault the High Heavens.
 Physical Appearance
Azmodan's appearance is meant to reflect his station as the Lord of Sin. He is extremely corpulent, personifying the sins of Gluttony and Greed. He appears to sit on six crab-like legs which, along with his torso, are opulently decorated with treasures and trophies, mirroring the sins of Pride and Vanity.
His face features a large, glowing mouth full of dagger-like teeth. His mouth also splits his face vertically, and on each side he has 2 eyes. From his back, two large horn-shaped appendages extend.
 Power and Abilities
Azmodan delights in tempting and corrupting others, and he is the most seductive and charismatic of all the Great Evils, despite his hideous appearance. He tempts others into sacrificing their beliefs and principles to give in to vice and sin.
Furthermore, Azmodan controls most of Hell's forces since the beginning of the Dark Exile, and is on this ground alone a force to be reckoned with.
