Biography
During the Silver Millennium, Serenity was fascinated by the Earth. Even though she was given orders not to go to the planet, she secretly visited there and met Prince Endymion. The two then fell in love.

During the Dark Kingdom's attack which caused the Moon Kingdom's downfall, Prince Endymion died protecting Serenity. She fell into an extreme grief due to Endymion's death, and committed suicide. Serenity's mother, the Queen, sealed away the evil and the moon in order to save the rest of the solar system, though unfortunately everyone involved on the moon perished.

Before her own death, the Queen used the Silver Crystal to give her daughter and others another chance at life, hoping in particular that, this time, Serenity and Endymion could find happiness together.

Serenity cared deeply for her sister, and soon began to notice that Andriette began to grow unhappy. One fateful night, Andriette's jealousy and hatred transformed her into Dark Star. They battled until Serenity was forced to use the Legendary Silver Crystal to defend herself and the people of the Moon by sealing her into what became known as the Starlight Moon Crystal. Things stayed this way for awhile, and Princess Serenity became Queen, abandoning the now derelict Moon Castle and creating a new castle. Year later, Dark Star managed to break free of her crystal prison and succeed in killing Serenity.
