The Lodestone Krystal was the sacred and mythical Krystal Of Power of the Odaku. The Lodestone was the symbol of the ancient Odaku rulers. After many years, it was lost somewhere in the Ramparts Of Ryousan and fell into myth.
During the Metal Ages, the Lodestone Krystal was found by Gorhagar in the the ruins underneath the Ramparts Of Ryousan. The discovery of the Lodestone legitimized Gorhagar's claim to the Odaku throne, allowing him to stop the fighting between the Odaku and the western armies.
