In every generation, a blood moon rises to the kingdom of Selenius to signify the birth of a new queen. As tradition, all royal daughters of the current queen shall join the pageant to determine who will sit on the crystal throne. This pageant would require each princess to fight with each other until death, leaving only one winner to be crowned as queen. But Queen Camilla refused to let her daughters to participate in this game, thus sending the four princesses to earth, away from the kingdom, away from the Selenes, away from the blood moon and away from sure death.
