In an audacious bid for power, the Cult of the Dragon along with its dragon allies and the Red Wizards of Thay seek to bring Tiamat from her prison in the Nine Hells to Faerun. To this end, they are seeping from town to town, laying waste to all those who oppose them and gathering a horde of riches for their dread queen. The threat of annihilation has become so dire that groups as desperate as the Harpers and Zhentarim are banding together in the fight against the cult. Never before has the need for heroes been so desperate.
