The Wyrmberg was an upside-down mountain where the dragonriders lived alongside their imaginary dragons. It was also the home of Liessa Dragonlady, Greicha the First of The Wyrmberg, Lio!rt Dragonlord, K!sdra, and Liartes. It was visited by Rincewind the Wizzard, Twoflower, the Discworld's first tourist and Hrun the Barbarian during an expedition across The (Unnamed) Continent. Rincewind and Hrun were both challenged to combat.
