Hundreds of years ago, an artifact was excavated from one of the ancient ruins. It was a Silvermoon-shaped stone that was said to be filled with magical power. That stone had caused Krissen IV to go to war for it against 7 other noble families and it was termed the Newmoon War or the Newmoon Chaos. In the end, Krissen IV won a hard-fought victory and eradicated the other 7 families. However, the magical stone had disappeared and was never seen by anyone else ever since. Having ruined half of his empire and gaining nothing, Krissen IV was often ridiculed for expending so much effort on something he did not get his hands on in the end.
