The Rainbow Princess

The Rainbow Princess was the princess of The Kingdom, she had ten knights who were all Magical Girls, they protected her & trained her on how to use her powers.

Life
Quartz was born to the King & Queen of a magical kingdom from long long ago, She was born a Magical Girl which meant she'd have magical powers as she grew up.

As a kid her loyal knights made her a friend, Bunbun a pet bunny who could talk & would never leave her side, the joy from feeling this loved helped kick start Quartz's powers, so soon after her training started

She was nearly 13 when the world came to an, monsters over took the kingdom and there was only darkness in the sky, her knights lay dying so Quartz did what she felt she had to, using her powers she made it they would reincarnate so they'd be able to that some point stop the force that destroyed the world. After the knights died Quartz was left alone numb waiting til the end, due the great use of power she was unable to feel anything, she spent that last hour with Bunbun til all life in The Kingdom ended, with the world she going to rule quartz died.

Legend
Due the great power she had along with her being behind that fact of reincarnation for The Magical Girls The Rainbow Princess has become quite the legend, some Magical Girls see this Rainbow Princess as some form of Magical Goddesses while other feel that she fated them to fight a never ending battle so see her was some form of devil, but as a whole these legends tend to over the fact that this Rainbow Princess was just a person who had powerful magic but otherwise was normal.
