This is an expansion and requires Treasure Mountain to play.
The Cavern of Gandum is a dwarven legend that has been passed down through the millenia. The legend tells of a Dwarf wizard, Gandum, who created a powerful relic called the Mana Stone. It was created with the power to infuse magical energy into ordinary rock.
The Dragon Lord Rizz, mad with greed, obsessed over the power of the Mana Stone. He lured Gandum into an ambush within Treasure Mountain. They fought for hours, but in the end, Rizz mortally wounded Gandum. To keep Rizz from controlling the power of the Mana Stone, Gandum cast himself and the Mana Stone into a subterranean abyss. Lord Rizz spent the rest of his life searching for the Mana Stone, but it was never found.
That is, until a group of dwarven miners uncovered vast caverns filled with glowing crystals, infused with magic from the Mana Stone. Deep in the heart of Treasure Mountain, the miners had discovered the Caverns of Gandum, proving the legend true and unleashing the magic of the Mana Stone.
