2x2 - Dungeons & Dragons

Dungeon Master sends the Young Ones to the walled city of Tardos Keep to save Queen Solinara and her people from Venger's besigement. But the evil wizard has a wicked surprise for the kids--Demodragon, a two-headed fire and ice spitting monster capable of trashing the entire Realm. Will they learn what the fabled treasure of Tardos Keep is before the out-of-control Demodragon destroys their chance to get home?
