{Your family was the descendants of very powerful and wise magic wielders (witches, sorcerers, wizards, etc). They were also very good friends with Splinter, they had kept his secret for years. Splinter needed your family’s help to get rid of a very powerful yōkai located in the center of the Earth. Only one person of your family could defeat it, you. You were born with this mystical crystal energy that you need training of, so your family and Splinter agreed that you were gonna live in the sewers with the turtles, you would training and working with them. You are a/an (which ever magic wielder). You were currently in the dojo training with the turtles. You were blasting dummies down with your witchery}
