In the era known as the Silver Millennium, three planets of the inner solar system and five planets of the outer solar system were chosen to be guardians of the Moon Kingdom. The outermost planets: Saturn, Uranus, Neptune, and Pluto would protect the entire universe beyond the edge of our own system. The four innermost planets: Mercury, Mars, Venus, and Jupiter, would watch over the Lunar empire, keeping trouble from harming the Royal Moon family. Four young princesses were chosen to take on this responsibility: Princess Ami of Mercury, Princess Minako of Venus, Princess Rei of Mars, and Princess Makoto of Jupiter. Each was sworn to protect Princess Serenity and to defend the Moon Kingdom against foes.

One planet remained separate from the others. This was Earth: the Moon's soul purpose for existing. The Lunar Kingdom's assignment was to watch over the Earth, to look down and keep darkness from covering the fair land. Due to this task, Lunars were not allowed to communicate or meet with Earthlings. Against the judgement of her senshi, Princess Serenity had fallen in love with the Prince of Earth, whom she was forbidden to love. Destiny has a way of bending and twisting rules to the snapping point. It was easily seen that the love they shared could not be kept apart.

For many years there was a blissful time known as the Silver Millennium. All was well in the Moon Kingdom. People were happy and the land was full of extravagant parties and lovely picnics on the Sea of Serenity. In this time the nine princesses forgot their guardian duties and were free to be starry-eyed teenage girls.

But not everyone joined in this peaceful state. Living on the Earth was a very lovely young lady. She was beautiful in face, yet dark in heart. This raven-haired lady's name was Beryl. For long she had pined after the handsome Prince of the Earth, Prince Endymion. At a ball in the palace, a heartbroken girl witnessed her love embrace another. But not just any other, the Princess of the Moon. A legendary love had sparked that night, and Beryl was there to witness it all. Instead of crying, instead of mourning over the loss of her love, instead of finding someone else to give her heart, Beryl chose to seek revenge. Metallia, a powerful swarm of energy fallen from an evil sunspot, was the one who promised her that chance. Together, Beryl and Metallia worked to destory the Terran dynasty. Gathering rebels from the Earth, they struck out with a force of jealousy and anger. Becoming aware that this rebellion was taking place, Prince Endymion sent word to the other planets and the finest warriors were sent to protect the Moon.

A brutal war would soon be set on the Moon. It would be the Lunars' last battle in the Silver Millennium. Desperately, the senshi tried to protect their princess, fighting Beryl's minions with a firey passion. Through all their bravery, something horrible occurred. Endymion was struck with a fatal blow. In her grief, Serenity pierced herself with his sword. It was then that Sailorvenus dealt the final, deadly blow that diminished the false Queen Beryl from the Silver Millennium.

Knowing that there was no hope that peace would regain its status on the Moon Kingdom, Queen Selenity used the last of her powers to seal Metallia with the Silver Crystal and to send her daughter, Endymion, and the senshi to be reborn on Earth. But things did not turn out as peacefully as she had anticipated...
