The game begins with Vahn, Adrianna and Kromlech arriving in Baldur's Gate, whereupon they are attacked by a group of thieves led by Karne (voiced by Michael Bell). The thieves are about to kill the trio when they are interrupted by the city watch, who take the newcomers to the nearby Elfsong Tavern to recover. There, the bartender, Alyth Elendara (Jennifer Hale), assists them in earning some money by giving them the job of clearing the tavern's cellar of rats. In the cellar, they discover the thieves are using the tavern's sewer entrance to infiltrate the city. When Elfsong Tavern employee Ethon, follows them into the sewers and disappears, they agree to Alyth's plea to find him.
Kite's friend Orca invites him to play The World. In the first dungeon they visit, they encounter a girl in white, Aura, being chased by a humanoid monster. Aura tries to entrust Orca with an item called "the Book of Twilight", but the monster attacks him, crashing The World's servers.
