Plot Overview as of March 26, 2022

The city of Elturel has mysteriously disappeared from the living realm, leaving a giant crater where it once stood.

The neighboring capital city of Baldur's Gate has locked its gates, not sure what has happened in Elturel.

Baldur's Gate's Grand Duke, Ulder Ravengard, was visiting Elturel when the city fell. A group of Flaming Fist mercenaries (the player's first characters) have been tasked to investigate his whereabouts.

They've uncovered a potential corrupt pact between the councilmembers of Baldur's Gate and the devils of Avernus, the first level of Hell.

The heroes find that the city of Elturel has been pulled into the realm of Avernus and Baldur's Gate may be next.

Meanwhile, a heroic group of fierce Hellriders of Elturel (the player's second characters) survive being pulled into Avernus. The Hellriders rescue as many citizens as they can and find that Elturel is slowly being pulled to the surface of Avernus by huge chains.

Beneath the city, a war between Devils and Demons rages on. The demon scourge is attempting to dethrone the ruler of Avernus, Archdevil Zariel, and take control of the realm.

The Flaming Fist group from Baldur's Gate teleports to Elturel in search of Ravengard. They join forces with the Hellriders to protect the innocent and save the city, as it is believed the city will permanently be part of Avernus if it gets pulled all the way down to the surface.

The group now has to find Ravengard, save the city, and dance around the infernal war between dark forces.
