The First Circle of Hell

Avernus is thelargest of the Nine Hells, and fits the classic vision of an infernal realm; raging volcanoes dot a land of lifeless and blasted rock, while rivers of blood and lava wind between vast, viscera-soaked fortresses. There is no sun or stars, only an endlessly roiling sky of dark clouds, lit by flashes of fire and an eternal reddish glow.

As the gateway between the Nine Hells and the Abyss, Avernus serves as the primary battlefield of the Blood War, the eternal conflict between Devils and Demons. The Lawful Devils and Chaotic Demons have been fighting for control of their respective homes since the beginning of time, throwing millions of monsters, soldiers, and slaves into a never-ending meat grinder. Avernus has been stained by this eternal battle, with blood soaked into every inch of the land, and the only major settlements being the vast fortresses of the Devils.

Although Avernus is the primary battlefield of the Blood War, commanders on both sides are always looking to the other realms for ways to end the permanent stalemate, and Blood War skirmishes can break out anywhere that Demons and Devils meet. It’s one of these schemes that leads to the events ofBaldur’s Gate: Descent into Avernus, a popularDungeons & Dragons Fifth Editionadventure module which thoroughly explores the blood-soaked first circle.

Avernus in Baldur’s Gate 3

Thestory ofBaldur’s Gate 3’s takes place a short time after the conclusion ofDescent into Avernus, and begins with players taking an unwanted trip to Avernus. Stranded on a mind flayer nautiloid, players take their first steps inBaldur’s Gate 3while hurtling through Avernus, pursued by both Githyanki dragon-riders and the combatants of the Blood War. Although the game’s tutorial section ends with the nautiloid returning to the Sword Coast, it won’t be the players last encounter with Avernus.

The descent inBaldur’s Gate: Descent into Avernusrefers to the fall of the holy city of Elturel, a Sword Coast city dragged into Avernus by the scheming of the Archdevil Zariel. Although Elturel has been returned to the surface by the start ofBaldur’s Gate 3, allTiefling residents have been driven outof the city due to their fiendish heritage. Players will encounter a large group of these Tiefling refugees early in Act 1, and can hear for themselves the story of Elturel’s descent into Avernus.

Soon afterward, players will get a chance to learn more about Avernus by encountering theTiefling Barbarian Karlach, one ofBaldur’s Gate 3’s Origin characters and a potential companion. A slave-champion of Zariel in the Blood War, Karlach saw the nautiloid’s arrival as a chance to escape her servitude and the endless violence of Avernus. Although she was implanted with a tadpole in the process, she did successfully escape, and when players meet her she is still being pursued by the vengeful agents of Zariel in the mortal realm. As players grow closer to Karlach and complete her personal quests, they’ll get the opportunity to learn even more about Avernus and the horrors of the Blood War.

Baldur’s Gate 3is out now for PC with a PS5 version coming September 6. An Xbox version of the game is also in development.
