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 Andariel.

“Andariel was the only female Evil. She aided the Lesser Evils for many years, but eventually she lost faith in their plots. Two decades ago, she chose to help Diablo during his resurgence and seized the Citadel of the Sightless Eye. Ultimately, she perished at the hands of brave heroes.” 

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


Andariel, the Maiden of Anguish is one of the four Lesser Evils (The other ones are Azmodan, Belial and Duriel). Andariel 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 her early days, Andariel used to rule the Realm of Anguish in Hell, under Diablo’s guidance. She is also the twin sister of Duriel and she is commonly known as the Demon Queen.

The four Lesser Evils (Azmodan, Belial, Duriel and Andariel)

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 in 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 Lord of Sin, Azmodan

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. After his defeat, Azmodan made a pact with Belial and, together, they asked Duriel and Andariel to participate in their stratagem to overthrow the Three. The twins had their doubts at first but Belial managed to convince them to join the rebellion.

The Second Rebellion and the Dark Exile

Believing that the main target of Hell was the High Heavens and not the control over humanity, the Lesser Evils 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.

Archangel Tyrael when the Prime Evils invaded Sanctuary

When the Prime Evils arrived in the mortal realm, the Archangel Tyrael immediately sensed their presence. He rallied several of the Mage Clans, the most powerful nephalem mages in the world, and together they formed an alliance known as the Horadrim. The Prime Evils could not be killed in the mortal world so the only solution was to bind them forever in an eternal prison. The Angels created the Soulstones, some powerful stones able to contain the essence of a Prime Evil. Soon, all the Prime Evils were captured by the Horadrim and sealed on the Soulstones.

Andariel’s Betrayal

Three hundred years after the Second Rebellion, Diablo finally managed to escape from his soul prison at the Tristram Cathedral in the form of the Dark Wanderer. When Duriel realized the power that Diablo possessed he immediately contacted Andariel. The twins believed that the Prime Evils would inevitably reclaim the throne of Hell so they asked Diablo to forgive them and let them join the Prime triad. Diablo accepted the twins pledged their loyalty to the Lord of Terror once more.

The Siege of the Rogue Monastery

Andariel volunteered to protect the fragile human form of Diablo, but the Lord of Terror had other plans for her. Diablo tasked Duriel with protecting his human host and sent Andariel to invade the citadel of the the Sightless Eye Sisterhood. This citadel was a key location for the Prime Evils because it connected the monastery with the eastern lands of Aranoch. Andariel stormed the Rogue Monastery killing many sisters in the process. She also mind controlled a portion of them, turning the noble women into mindless abominations that served her.

The catacombs of the Rogue Monastery

Quickly, Andariel prevailed and took control over the Rogue Monastery. That victory allowed Diablo, in his human weakened state, to safely cross the underground passage of the citadel and arrive in the Eastgate. Andariel sealed the citadel and ordered her demon lieutenant, the Slayer, to guard the path between Waystruck and the Rogue Monastery. She hid in the catacombs in order to protect the passage and buy time for the Lord of Terror to free his brothers.

Andariel’s Fall

Years later, a group of adventurers in search of Diablo entered the Rogue Monastery. They attacked the fallen sisters and they managed to reach the catacombs. In the fourth level of the catacombs they encountered Andariel. The Maiden of Anguish not only struck out at her foes physically but battered them emotionally as well, stirring within each of the memories of loss, sadness, betrayal, regret, guilt, even as she fed upon on their anger and relished in their despair. However, the group of heroes managed to maintain their sanity and defeat the Demon Queen.

The Black Soulstone

Andariel’s essence ended up in the Black Soulstone after Adria’s interference. The Maiden of Anguish was later merged with Diablo as a single Prime Evil but managed to break free again because of Malthael. The exact location and state of Andariel is currently unknown.

I plan on making one Warcraft lore post and one Diablo lore post  per week (I’ve started a YouTube channel as well and hopefully I will upload my first lore video in August – September).
