Morgana's kids had kids, and they would continue the tradition of being rulers of this world. Each ruler all praised equally the same. One ruler, though, was different. His name was King Augustus, and many considered him to be a tyrant. He had many controversial opinions, and he treated his subjects with disrespect. One day, everyone had enough and the people rebelled, they all fought to overthrow the king and they succeeded. He died, but his children had to hide away for years. His daughter gave birth to twins, Luna and Magnus, who she believed would save the Royal family and redeem them. They eventually became sibling rulers, and proved to everyone they weren't like the tyrant king. The King and Queen both found love. The Queen had no children, and the King had 1 son with a mermaid. The spirit of the tyrant king wasn't pleased with this, and cursed the king and his son. This cursed made it impossible to use their magical powers, as it would do damage to them.
