Moon Kingdom

The **Moon Kingdom** was an ancient civilization that existed on the moon since prehistoric times. It boasted prosperity and everlasting peace. With Queen Serenity as its monarch, it was the pique of Silver Millennium and held the all-powerful Legendary Silver Crystal.

## Legacy

Silver Millennium was ruled by Queen Serenity, the incarnation of the Moon Goddess Selene, who had two daughters named Princess Serenity and Princess Luna. Princess Luna was heir to the throne of Silver Millennium, which had a sacred duty to watch over the Earth, as well as protect the family heirloom, the Legendary Silver Crystal. The Four Guardian Deities of the inner solar system (Sailor Mercury, Mars, Jupiter, and Venus) were entrusted to be Serenity's personal bodyguard and court, attending and watching over her at all times, as well as serving as a basic defense system for Silver Millennium as a whole. Princess Serenity fell in love with the Earth, and longed to feel the wind and trees. Eventually, Princess Serenity fell in love with Prince Endymion, the ruler of the Earth Kingdom. At one point, Princess Serenity gave Prince Endymion a mystical star-shaped locket, which played an instrumental version of Moonlight Legend. It was implied that this locket was imbued with the power of Serenity and Endymion's love, and Mamoru Chiba held the locket in the modern day. After dropping it during a battle, Usagi Tsukino picked it up and kept it with her for the majority of the season. Although Moon Kingdom people were forbidden to meet with those of Earth, Serenity met Endymion in secret at a ball. Unfortunately, the people of Earth were brainwashed by an evil entity, who convinced members of the Earth Kingdom to launch an assault against the Moon Kingdom. Queen Beryl led the assault against the Moon Kingdom, and she created a organization dedicated to destroying the Moon Kingdom's legacy, with Metalia as it's leader. This organization was known as the Dark Kingdom, and consisted of the Four Kings of Heaven, herself, and Queen Metalia. Despite Sailor Mercury, Sailor Mars, Sailor Jupiter, and Sailor Venus' attempts to defeat Queen Metalia, the Moon Kingdom fell during the assault. Queen Metalia eventually found the opportunity to launch a direct strike against Princess Serenity and Prince Endymion, killing them both and causing great agony and trauma for Queen Serenity. Left with no other option, Queen Serenity used Moon Healing Escalation with the Legendary Silver Crystal's power attached to it to seal away the Dark Kingdom. Princess Luna also died in the attack due to Jadeite stabbing her in the chest. Unfortunately, the process of doing so drained her life force. Using the last of her remaining life, Queen Serenity reincarnated Princess Serenity, Prince Endymion, and the Inner Guardians on Earth, to be reborn in a more peaceful era. Princess Serenity and Prince Endymion eventually awakened as Usagi Tsukino and Mamoru Chiba, respectively, due to the recently revived Dark Kingdom. However, Mamoru was brainwashed into becoming a soldier of the Dark Kingdom, using his past alias, Endymion. After a prolonged battle against Endymion, Usagi was able to restore Mamoru to his old self. to restore Mamoru to his original self. Usagi then transformed into Princess Serenity and fought Super Beryl.

## Revival

In 1992, in Tokyo, the Dark Kingdom began hunting for the Legendary Silver Crystal, led by Queen Beryl, in order to revive Queen Metalia from her seal placed by Queen Serenity. While Jadeite and Nephrite were only able to gather relatively small amounts of energy, their efforts were enough to partially stir Queen Metalia. She told Beryl that to find the Silver Crystal, they must locate the Rainbow Crystals. Zoisite almost succeeded in gathering all seven, however, Mamoru Chiba was injured during an attempted assault on Sailor Moon, causing her to awaken as Princess Serenity, witnessed by all of the Inner Guardians and Zoisite. Later on, Usagi's memories of being Princess Serenity return, and she remembers Endymion's sacrifice to save her. In the Sailor Luna story, it claims that Yuri awakened well after Usagi did but the outers knew about Yuri's past and protected her as well as the Solar System.
