Foil the minions of Tiamat or be enslaved!
Hoard of the Dragon Queen(TM) pits players against evil dragons, the Cult of the Dragon, and the Red Wizards of Thay, which are conspiring to seize power in the Forgotten Realms. By bringing Tiamat, Queen of Evil Dragons, to Faerûn, the forces of evil hope to claim dominion over the free peoples of the world.
