The player begins by clearing the tavern's cellar of rats and vermin, and later discovers a thieves' den in the sewers  where it is learned that one of the guests at the inn has been captured by thieves. Delving further into the sewers, the player finds an entrance to the crypt  of the local temple where the dead are being reanimated by a magic orb, which must be destroyed. The destruction of the orb leads to meeting Jherek, leader of the Harpers, who tells the player that the Thieves' Guild is only one "part of a greater whole", and the guild must be destroyed. The player then infiltrates the guild's secret lair, defeats Kharne (associate of the Zhentarim and the second-in-command of the thieves who had ambushed the player at the start of the game) and meets Xantam, a beholder  who reveals that he is controlling the thieves' guild on behalf of some greater power. After defeating Xantam, the player finds a portal which transports him away from Baldur's Gate.
