The Cabal is a side quest that begins and ends once Gorion's Ward enters the ruins of Kanaglym in the Underground River in Baldur's Gate: Siege of Dragonspear. Upon entry to the city, the player will see a number of necromancers using a portal to the Fugue Plane to convert living victims into undead monsters. Upon sighting Gorion's Ward, the necromancers will go hostile. Once they have all been slain, the party will receive the quest EXP and an entry in the journal about defeating the Cabal.
