In the realm of Astoria, there are two kingdoms. Solaria and Etheria. Solaria is the kingdom of light, of eternal day, and it is ruled by King Solter. Etheria is the kingdom of darkness, of eternal night, and it is ruled by Queen Crescent. 19 years ago, the former kings and queens of Solaria and Etheria wished to unite their kingdoms. To achieve this, they decided to wed their two heirs. However, Solter refused to marry Crescent as it was not for love. Now it just so happened that Crescent had a younger sister named Luna. Luna had the most beautiful purple eyes, and Solter fell in love with her. They were married shortly after and started to try for a child. After two years, Luna finally fell pregnant, and soon delivered two baby girls – twins. One for the day, one for the night. Each with the same eyes as Luna. Crescent was furious, and decided to seek revenge. She snuck into the castle of Solaria with a green gas that made everyone but Luna and the night twin sleep. In that moment, she tried to steal away both of the princesses but was stopped by her sister. Luna managed to save the day twin, but was knocked by Crescent and plummeted to her death. She cushioned the fall for the day twin, who grew up in princess life, although she was unaware of her past. The night twin grew up under Crescent’s rule, thinking herself a simple servant. With his beloved Luna gone and his youngest daughter stolen, Solter was devastated. But his Grand Sorceress Caasi told him that as long as the Sun Amulet and the Moon Amulet were kept away from each other, Astoria was safe. He foretold something from when the twins were 16. “When the hearts of day and night come together in love, the world is one.”
If someone joins, I shall post a template and a proper plot.
Also I'd like to be the Solarian princess, but I'm OK with the Etherian one.
