In a world unknown to the present people, long, long ago, there existed two magnificent kingdoms. The Moon Kingdom, ruled by the beautiful, wise Queen Serenity, and the Kingdom of Avalon, governed peacefully by the majestic Queen Anya. The Moon Kingdom was fascinating and full of diverse surprises found nowhere else in the galaxy. It was, however, a young empire, so new it did not have a monarch for any of its nine planets, for only Queen Serenity ruled this vast kingdom from the moon of the third planet from the sun, hence, the name Moon Kingdom. It was eventually decided that each of her eleven daughters, coming of age, would be sent to their own planet to live out their lives and become that planet's first legendary monarch.
The eldest daughter, Setsuna, became Pluto's new princess. Her forehead bore the crest of Pluto at birth. A mysterious girl, like her planet, she had black hair that was tinted with a dark green, and scarlet eyes that revealed nothing except which she chose to reveal. This came in very handy when appearing to people in dreams, to warn them of danger, or for any other purpose involved in these visits.
A year later, twins came, the beautiful, talented Michiru, on whose forehead gleamed the symbol of Neptune, and the strong, tomboyish Haruka, bearing the symbol of Uranus. Michiru was artistic and musical, and perfectly fit for the aquatic planet Neptune, being extremely skilled in swimming. She had sparkling aqua eyes, and wavy green hair that cascaded down her shoulders in ripples. Haruka loved athletic activities, and was tomboyish almost before she could walk. Haruka had short blond hair, cut in a boyish fashion, and bright blue eyes. Though dramatically different, Michiru and Haruka were inseparable from their first moment in life.
Two years passed, then another pair of twins followed, Jenny and Tammy. Extraordinarily, both of their foreheads showed the crest of Earth. The choice was very easy - those two would become the first known co-rulers of a kingdom. Jenny was born with Light brown hair and beautiful light brown eyes while Tammy was born with Rich Dark brown hair and hazel eyes.
The most unique of all Serenity's daughters, quintuplets arrived. Ami, with Mercury's symbol on her forehead, Minako, on which glimmered Venus, Makoto, with Jupiter's crest emblazoned on her forehead, Rei, on whose forehead blazed Mars' fiery crest, and Usagi with a magnificent crescent moon shining brilliantly on her forehead. This was what Serenity was waiting for. Usagi was the new heir to the ultimate throne, the topmost monarch, the new ruler of the entire Moon Kingdom. This was a continued frustration for Rei, who, for the life of her, could not understand how the klutzy Usagi could ever be the ultimate monarch. Ami was quiet and intellectual, with soft blue hair and matching blue eyes. Minako was lovely, with blond hair and blue eyes, with an infectious smile included. She was always cheerful and happy, which was very helpful when someone needed cheering up. Makoto, very much like Haruka, was tall and strong, but, very unlike Haruka, she was boy-crazy as soon as she opened her eyes. She was forever chasing after the knights-in-training who lived in the castle. She had brown hair and pretty green eyes. Rei was very similar to her planet, with a fiery temper and a smart attitude. She had long black hair with a touch of purple, and beautiful purple eyes. Usagi also had blond hair, like Minako, but instead of deep blue eyes, hers were sky blue and very pretty. It was a kingdom joke that the only identical pair in the sea of royal twins were Minako and Usagi.
Last but not least, Hotaru came, the Saturn princess. Perhaps Serenity had simply run out of energy, with so many daughters, but Hotaru was frail of health and very delicate. She had black hair, cut in childish chin length style. Only Minako and Usagi looked alike, none if the others had any resemblance whatsoever. It was mystery that perhaps no one would never solve.

The Avalonian princesses were far simpler to explain. They were Gwenevere, Tammara, and Fallon. Princess Gwenevere was born with blond hair that went to her waist, Tammara was born with light pink hair that also went to her waist. Fallon was probably the most odd of these princesses she was born with purple hair that goes to the middle of her back.
Queen Serenity and Queen Anya had long been the best of friends, but unfortunately, the princesses had never met one another. They all knew of the opposite kingdom, but the two Queens had never told them about their counterparts.
"Serenity?" Anyas voice suggested power and confidence, firm, yet kind.
"Yes?," Serenitys voice, in turn, was gentle and graceful, able to sooth any distress at the very sound. They were sitting in the royal throne room of the Crystal Palace, where Queen Anya ruled.
"I would like you to allow the princesses of your kingdom to become Jewel Riders. They may choose another companion to become a Jewel Rider with them, if they wish." Queen Anya paused. "Several days before, I contemplated an invincible force, able to destroy any danger that would fall in either of our paths. This combination may be able to create that force."
Queen Serenity looked thoughtful. "I give my consent," she said at last. " But I can guarantee you nothing, Anya. These are adolescent girls. Three of them are nearly adults. They must be given their own choice. You must agree, my dear friend. I know you have experience of your own."
"How incredibly true." Anya replied, smiling. "Time flies faster than my Jewel Riders can. I must say, you were always the practical one." She stood. "Very well. I will await your kingdoms reply. It is quite late. I think you must be getting back to your own kingdom, dont you agree?"
"Completely." Serenity laughed. "We can still read each others minds, cant we, Anyie?" She said, using her old nickname for Queen Anya.
"I would agree, were it not for the fact that you have once again used the nickname for me that you know I detest." Anya said, feigning anger.
"I oblige, Anyie, my liege." Serenity said, laughing harder. Anya practically chased Serenity into the portal back to the Moon Kingdom.
"Who would know Serenity would be capable of these things?" Queen Anya sighed, half laughing herself.
