Hidden well beneath the great mountains, there exists a gloomy and gargantuan cavern inhabited by the dark civilizations of the world. Goblins, Dark Elves, and Dark Dwarves build their armies and thrive in the empty spaces between the stone. Your mine will dig deep and reach the fabled Underdark. Will you navigate the dangers of the Underdark and survive in the dark place beneath the mountain? Or will the dangerous creatures spell your doom. Play to find out, as your mine tells its story!
