Those new to D&D lore will be confused by the events, so this is an 'executive summary' of the key points you must understand:ġ) Mindflayers 'reproduce' by infecting other races with 'tadpoles' - after a certain time, the creature will take control of the host and convert it into a Mindflayer. You will then see a group of Dragon Riders teleport into this space to attack the ship, which triggers a chase scene across realms. When you first begin Baldur's Gate 3, you will be treated to an intense cinematic depicting a Mindflayer and its ship, and their assault on the city. The game is based on the 5th edition ruleset of D&D and was created closely together with Wizards of the Coast. In our canon, it was saved by a party of heroes.

The holy city of Elturel disappeared from the Forgotten Realms and descended into Avernus, the first layer of the Nine Hells.

Baldur's Gate 3 takes place right after the events of Descent into Avernus.
