Available only through core hobby game stores, Tyranny of Dragons is a single special volume re-release of the two-part adventure from 2014 featuring a new cover designed by Hydro74. The 224-page adventure combines the two previous titles (Hoard of the Dragon Queen and The Rise of Tiamat) into one book, taking players from level 1 all the way to level 16 as they contend against the Cult of the Dragons plans to bring their queen Tiamat to the Forgotten Realms.
