Over the next few days, Rei learnt more and more about her mission and the story behind it. Back before the invention of writing, Earth had been home to a very wise and advanced civilisation. As we're all the other planets in the system. Then one day, another planet had drifted into Earth's orbit, becoming the Moon. The people of the Moon (maybe there was something to the old stories) had united the planets of the solar system into a large empire known as the Silver Milennium. The planets had all appointed one of their princesses to serve as guardian soldiers intended mainly for combat and scouting missions. These were known as the Senshi. Rei was the reincarnation of the last holder of the Sailor Mars title.
Then things changed once Earth decided to join after hundreds of years putting off. Their ruling prince, known officially by the title "Endymion", was betrayed by those closest to him. His bodyguards had allied with an evil witch, who served a dark force. The various planets were purged of life, until only Earth and the Moon were inhabited. The Mau people had detonated their planetary core to try and stop the creature, but to no avail. Luna and her companion Artemis were the only survivors, having left the planet for service years before. The evil force had destroyed the moon, but the incumbent monarch, Queen Serenity, had used the power of the Illusionary Silver Crystal (did this thing really exist?) to seal them away in a polar based prison. But knowing they may yet escape, she had sent the various deceased forward to be reincarnated in the future, ending her own life in the process. Now Rei had to find the others, unite with Sailor V and save the world from a powerful, dark god. No pressure, then!
Jadeite reported to his superior officer, Kunzite. The two of them had always disliked each other, even when they served the paltry prince of the Earth.
"Sir," Jadeite began, "the operation's failure was not my fault. My servant sensed there were people who would interfere with the operation, people who had, as the humans say "Sussed it out". I retrieved what little energy I could collect and sent her to perform a routine elimination. How was I to know that the target was one of the Sailor Senshi, let alone that there was another one. But don't worry, I have other operations in…"
"Silence!", bellowed his immediate superior. "I can get Queen Beryl to overlook your failure this time. I myself have also had trouble with another Sailor during my operations in England. It seems more of her lot have chosen to make themselves known. So continue with your operations for now, Jadeite." He dismissed his subordinate "I have one of my own. I will find one of the others and turn them into a powerful ally. Why didn't I think of the potential before? A Senshi on our side would be beneficial. And who am I talking to?" Then he dismissed his own question and went to recruit someone who could be of assistance.
