The Dungeon of Dragons is a 3-5 hour adventure for 16th-level characters. As members of the dragon hunters known as the Hand of Arahn, the party will be dispatched to follow up on reports of unusual dragon activity.
The players will find themselves facing completely new foes, and it will take every ounce of courage they have to defeat Uvaira, the Chaos Dragon from Limbo.
