Act One

Act One of Baldur's Gate 3 begins immediately after the events of the Prologue, following the Nautiloid crash and the player character waking up on the Ravaged Beach.
While the player character gathers allies and searches for a cure from their Illithid tadpole, a conflict is building between the Emerald Grove and a goblin army that is gathering under the banner of the Absolute.
