The Kingdom

The Kingdom is a place outside the retch of almost everyone, Only Space and Time Magical Kids are able to go to it

Past
Long, long before the start of earth The Kingdom was a kingdom on a plant whose name is long forgotten. It was a place full of both magical girls and boys, along with witches. it was ruled by a king and queen with their daughter who was a magical girl herself.

The royal family was protected by ten magical girls who acted as knights for the princess, they also trained the princess on how to use her powers.

Life in the kingdom ended when Nova came, the Knights tried in vain to fight off Nova but were unable to beat her, before all life from the kingdom was gone the princess casted a powerful spell, the ten knights would be reborn again & again for as long as they felt work wasn't done to protect the next world from evil and harm this spell costed the princess her life though it did work the Knights were reborn once there was human life on earth, the only other being who lived (in one way or another) was the gifted bunny also known as Bunbun

Present
At the moment the kingdom is in a place outside time and barely within space. Only Space Magical Girls can get there & only Time Magical Girls are able to go to the past of the kingdom.

Due to the fact that The Kingdom lays in a small but different universe time works differently then it does on earth, for every minute that passes in the kingdom only a second pass on earth. (so like while Ruth/Luna was in the kingdom for what seemed 7 days on earth she was really there for 420 days) Due to the fact the place lays in place with no life it also means while in The Kingdom nothing can grow and nothing can die, so if you come into The Kingdom stabbed you will not die nor will you heal
