Something is happening at the Spine of the World. A band of adventurers is hired to investigate a lost caravan. They soon discover strange events that sprawls into a plot threatening the entire of Faerûn - roughly 90 years before the events of Baldur's Gate.

The game allows players to create their own characters or choose from a selection of pre-made ones, each with their own unique abilities and skills. Similarly to Baldur's Gate, both games take place in the Forgotten Realms (a campaign in Dungeons & Dragons universe) with real-time combat and pause - allowing players to take time to strategize and issue commands to their party members during battles. The game also emphasizes exploration and puzzle-solving, with a variety of quests and side-quests to complete.
