Swords of Sun and Moon

Princess Selene of Lunaria loves to travel. She traveled many lands and kingdoms of Kria, except their rival kingdom, Sol. For seventeen years, Selene was so curious about the Solians. Her father, King Malcolm never allowed her to take a look of the kingdom, afraid that his only daughter will get hurt after Selene's mother, Queen Alice and younger daughter, Allie died because of a blade that can only found in Sol. Selene escaped from Lunaria and rode on a horse to get to Sol, but she got into a sword-fight with a boy who was actually Prince Lucas of Sol. He invited her to his birthday and without thinking twice, Selene agreed. At the party, she met Lucas's father, King Harold, Queen Natalia, Lucas's step-mother and his older sister, Kate. Selene was totally creeped out by Kate because she keeps muttering 'Swordsman' to her. Suddenly, a fog drifted into the town square and Selene was kidnapped! When she woke up, Selene found herself lying on the cold tiled floor in a room with Lucas who was kidnapped, too. Kate appeared before them and explained everything that their mothers were Swordsmen of Sun and Moon who wields the Swords of—well, Sun and Moon. She told them that they were the only one who can stop the Unknown Dark Queen to stop Lunaria and Sol from fighting. Could they defeat the Unknown Dark Queen? Or they will argue like their two kingdoms?
