The Diablo Lore series is a collection of articles delving deep into the history of many important Diablo figures and events. Since Diablo’s story is ongoing in the famous ARPG, I will try to constantly update these articles. I started with a Warcraft Lore series but I decided to give Diablo a chance as well, since its lore is really interesting. The following article will inform you about the Lesser Evil Azmodan.

Let me know in the comments about any errors or inconsistencies you may find. Feedback is greatly appreciated. Enjoy!


Azmodan, the Lord of Sin, is one of the four Lesser Evils (The other ones are Duriel, Belial and Andariel). Azmodan was born from one of the seven heads of the ancient evil dragon Tathamet. When Tathamet fell, every one of his heads became a Great Evil. Great Evils are separated in three Prime Evils and four Lesser Evils. In his early days, Azmodan used to rule the Realm of Hatred in Hell, under Mephisto’s leadership.

The Duel with Tyrael

During the Pandemonium Fortress battle, Azmodan managed to kill several angels, although they tried to outmanauver his attacks with their wings. Upon seeing all these deaths, Archangel Tyrael decided to end Azmodan’s advance by facing him in a duel. Azmodan was really strong but he was no match for the Archangel. Tyrael defeated the Lord of Sin and was ready to deliver the killing blow, but luckily for Azmodan, when one of the nearby angels called for help, Tyrael spared his life in order to help his comrade.

The First Rebellion

During the Sin Wars, the three Prime Evils kept the existence of Sanctuary and the nephalem secret from the Lesser Evils. When Azmodan found out about humanity, he lost trust in the Prime Evils and began to investigate further. Soon, the Lord of Sin found out that the Prime Evils’ main concern was their influence on the nephalem and not the Great Conflict anymore. This outraged Azmodan who decided to rebel against the Prime Evils by creating an army of demons.

The Fallen Ones cursed by Diablo

When his army was fully assembled, Azmodan moved against Diablo the Lord of Terror. However, his coup attempt failed and Diablo cursed Azmodan followers, turning them into the Fallen Ones. The infuriated Azmodan held them responsible for the Prime Evils’ continued reign, and so he left the fallen in their new bodies, where their degradation would serve to amuse him for all eternity. Luckily for him, the fallen demons had nonetheless provided him with valuable information about the Prime Evils’ empire.

The Second Rebellion and the Dark Exile

With all this new information, Azmodan contacted his brother, the Lesser Evil Belial, Lord of Lies. Believing that the main target of Hell was the High Heavens and not the control over humanity, the two brothers began a second rebellion against the Prime Evils. Although the Primes exacted a heavy toll on the rebels, they were, in the end, banished to the mortal realm, weakened and bodiless. Azmodan believed that with Diablo, Mephisto and Baal set loose in the mortal world, Heaven would switch their focus to the mortal plane, leaving them vulnerable to his attacks.

However, soon Belial and Azmodan started fighting over the throne of the Burning Hells. They turned on each other and their pact was forgotten. The armies of Hell were divided into two, leaving Azmodan powerless to take over the High Heavens with only half of his army left and Belial laying siege on his fortress. Thus, the second civil war in Hell began. After many years, the two Lesser Evils finally made a truce and realized that humanity was the key to victory all along.

Belial, the Lord of Lies, in Diablo 3

The following paragraph is a small spoiler so proceed with caution. Mephisto had orchestrated these series of events and the Prime Evils were exiled on purpose from Hell. Their goal was, through the soulstones, to corrupt the Worldstone. If they managed to corrupt the Worldstone they would be able to take control over the nephalem, retake Hell and win the Eternal Conflict once and for all.

The Fall of Azmodan

During the Diablo 3 events, when Belial was defeated at the hands of the adventurers, Leah had a vision of Azmodan, where the Lord of Sin revealed that he intended to invade Sanctuary in order to reclaim the Black Soulstone. With the Black Soulstone, Azmodan planned fusing with the Great Evils in order to become the sole Prime Evil. The vision soon became reality with Azmodan’s forces arriving at the Arreat Crater and laying siege to Bastion Keep.

Azmodan’s most trusted lieutenant, Ghom the Lord of Gluttony

Steady but slowly, the mortal champions managed to defend and push Azmodan’s forces back to the Mount Arreat crater and through the portal. Two of Azmodan’s strongest lieutenants, Ghom the Lord of Gluttony and Cydaea the Mistress of Lust fell in battle with the Nephalem. After several fights, the nephalem confronted the Lord of Sin who was defeated and his spirit was sealed forever within the Black Soulstone. He was the last of the Great Evils to be locked in that stone.

Thanks for reading! I plan on making one Warcraft lore post and one Diablo lore post  per week (hopefully some videos in the future). If you enjoyed the article and want to support me, feel free to throw a like on my site’s Facebook Page and a follow on Reddit.
