Unmanned Rock

The ghost stone (mujinseki) is a mineral ore found in the Dark Continent that has the capacity, once submerged in water, to generate electricity. Just a bead can put out about 20,000 kW of power for a day. It is found in the mountain ranges of the northeastern shore of Lake Mobius. However, this is also the territory of one of the Five Great Calamities, Papu. In the past, the allied nations of Begerose attempted to retrieve the stone, but of the 1000 people sent, only 7 returned.
