First Senshi: Sailor MoonThere was a legend known to all Lunarians of a silver crystal with untold powers. Whoever was able to find this crystal and wield its power would become the ruler of the Moon and be able to defeat Chaos and bring order to the galaxy. Things are never simple with legends and the silver crystal was no exception.More Like This
Only a woman could wield the power of the legendary silver crystal meaning the ruler of the Moon would be a woman, which did not sit well with the elders of the clan. Once the crystal was in the possession of its rightful owner the woman could only bear one child and that child would be a daughter. Finally, using the crystal to its fullest power would mean certain death for the wielder.
Anyone could hold the silver crystal but it would only react with the rightful owner. This meant one could pass the legendary crystal all their life and never know it.
