Ritterorden

Crystal stones, considered treasures of the Church, are instruments through which the power of God can be manifested. These stones are lent by the Church to Ritterorden's many countries and nations in a claim for legitimacy and power. The great nation of Stiode is the recipient of one of these stones: the crystal stone of Shadow. These stones serve as emblems of order and authority in time of peace and as weapons of great power in times of strife. On one side, are the holy knights who use these stones. On the other, a purple-haired girl who searches the world to destroy these stones. This story begins when the sides meet. [Lightly translated/adapted from developer site.]
