After arriving in Luskan, the protagonist hears rumors that Aribeth has defected and joined the cultists. These fears are confirmed when she is found meeting with Maugrim and Morag, Queen of the reptilian Old Ones. They seek a group of magical relics called the Words of Power. The protagonist retrieves all of the Words of Power except for one held by the cult. The hero discovers that the Words open a portal to a pocket world inside the Source Stone, where Morag and the other Old Ones sealed themselves long ago to avoid extinction during a primordial ice age. The protagonist confronts Aribeth, and depending on how the meeting is handled, she either surrenders to the PC or they are forced to kill her. The hero battles Maugrim for the final Word, then uses the Words to enter the Source Stone and battle with Morag. After Morag's death, the protagonist escapes the Stone as the world inside it implodes.
