> Tiamat returns to Dungeons & Dragons this fall. To celebrate the fifth anniversary of its Fifth Edition ruleset, Dungeons & Dragons announced that it would be re-releasing its first Fifth Edition storyline, Tyranny of Dragons, as a single volume this October. Tyranny of Dragons will collect Hoard of the Dragon Queen and Rise of Tiamat, the two adventures that kicked off D&D's Fifth Edition back in 2014. The adventure pits players against the sinister Cult of the Dragon and their quest to bring back their dangerous god Tiamat back to the Forgotten Realms.
