The Moonstone is the source of the Moon Goddess's power and what keeps the balance in the Moon Kingdom in check. There is a light side and a dark side. The Moon Bear King took the moonstone and separated them to their two parts. A yellow/white moonstone that represented the light and a purple/black moonstone that represented the darkness. The Moon Bear King kept the dark side and smashed the light side to pieces, otherwise known as the Moonstone Shards.
The Moonstone Shards are pieces of the White Moon Stone, which was broken into 12 pieces by the Moon Bear King, where he gave one to each of his Twelve Generals for safe keeping. Some of the generals also used the shards' powers for there own goals.
