Crypt of Kelemvor
In the Age of Demons, the island of Ice Shear was beset by dark and malevolent forces. But among the dwarves who lived there, there was a brilliant inventor named Kelemvor. He used his keen intellect and mastery of mechanics to create one of the most ingenious devices of his time - a clockwork dungeon designed to imprison the frozen demons and keep them at bay.
Kelemvor's clockwork dungeon was a marvel of its time, and its creation was a testament to his ingenuity and determination. But after the island froze over, the knowledge of the dungeon was lost to history. It was only rediscovered years later by Bazil the Bizarre.
The Crypt of Kelemvor is not without its dangers, however. The demons trapped within are still powerful and malevolent, and those who venture too deep into the dungeon risk being caught in the demons' icy grasp. The intricate mechanical traps and puzzles designed to keep the demons imprisoned could easily ensnare the unwary adventurer.
