Selene, Goddess of the Moon, after a long and fruitful reign over the pale Moon of the Life-Planet Earth, at last gave birth to a daughter she made her heir. Selene named her daughter Euryphaessa and taught her everything she knew about her guardianship of the night, about protecting travelers by ensuring the Moon’s secure glow, of answering the prayers of those who believed. Euryphaessa studied diligently, loving her future role and the people she would guide in place of her mother when Selene passed on. As her tutorship continued, Selene changed the Moon’s purpose, wanting her daughter to be known and loved for her efforts. And so the Moon Kingdom was born. Taking people from Earth and settling them onto the Moon in a space of her own creation, Selene gave Euryphaessa a kingdom to rule, a people to love and cherish her as she loved and cherished the souls of Earth. When finally she felt things were ready, Selene moved on, taking her rightful place amongst the gods and goddesses of old in their place of honor in the afterlife.
 
However, Selene’s passing did not go as smoothly as she had hoped, and Euryphaessa’s first duties as Queen and Guardian were challenging, for as Selene disappeared so, too, did her gifts and magic, and anything they had brought into being. Euryphaessa’s world was falling apart before her eyes, and there seemed to be nothing she could do to stop it. The air on the moon was escaping, her people slowly suffocating… it was then, when times seemed most desperate, that Euryphaessa discovered the beautiful clear gem her mother had left behind in her passing. It was spherical and multifaceted and held a beautiful silver sheen; immediately Euryphaessa knew it belonged to her, as it would belong to all who came after her. Reaching into it with a soft yet firm mental touch, she pulled and willed the power forth from it, shaping it to her wishes and restoring the kingdom her mother gave her.
 
Euryphaessa’s life was filled with wonders as she explored the Illusionary Silver Crystal and all it could do. Through its power she erected the Crystal Tower, a shrine she and her daughters could pray to in times of dire need, waking the will of her mother Selene and the very will of the Moon as a celestial body. Times were good, but after several millennia of life, Euryphaessa, too, felt it was time to move on. She had two daughters during her reign – Nyx and Theia – and gave her kingdom and the Silver Crystal to her eldest as she passed.
 
And so Nyx became Queen of the Moon Kingdom… and their first civil war was at hand. Nyx was a beautiful woman, beautiful and confident and vain. Where Theia, the younger, believed in justice and the good inside of everyone and had the drive to back up her beliefs, Nyx was prone to insecurities and succumbing to the darkness within her. The Silver Crystal, following Nyx’s heart, began to twist their world, to darken it and the hearts of the people around them. Theia, staying strong against the emotional attack by the Crystal and its wielder, was soon found by a group of Moon citizens and made to be their beacon of hope. Together they fought against Nyx and her loyal followers even as Nyx spread fear and terror on Earth, creating a rift that was nearly irreparable as time wore on; still, Theia and her loyal followers won out, taking the Silver Crystal away from Nyx and her Lunar power with it. Nyx and her court were banished to the other side of the Moon, their lives spared out of the goodness of Theia’s heart, but even her forgiveness had its limits. Using the power of the crystal, Theia partially sealed her sister’s court away within the Moon, forever to be kept on the Lunar surface facing away from the beautiful blue planet, and safely keeping the vulnerable people of Earth out of her sister’s sight.
 
Theia ascended the throne of the Moon Kingdom and took a commander of the Lunar resistance, a man named Okeanos, whom she had fallen deeply in love, as her King. In the 600th year of her reign, Queen Theia and King Okeanos gave birth to their first and only heir, a beautiful daughter they blessed with the name Serenity. However, Serenity was not the only new daughter of Selene; it was not long after their announcement that Nyx came to Theia in a mirror, announcing the birth of her own daughter, Nehelennia, and her intent to once again rule over the Moon Kingdom and possess the Silver Crystal for herself. While Theia and Okeanos’s baby was well-loved by their people from her first breath, in order to ensure her protection against those of the “Other Side”, Theia reached deep into the depths of the Silver Crystal and awakened the senshi of the outer planets – those blessed by the gods of the three realms: The Sky, the Sea, and the Underworld. When these senshi appeared before her, Theia held up her child before them and asked that they keep her safe; the senshi, feeling a soft adoration for the child, agreed.
