Tales of the four sisters

This is an outline for a book like a thought bubble

Magic has always be a recourse in out kingdom.
Since the signing of the witches of the east to allow magical people to live with regular humans.
There was a treaty, signed with all the realms of the kingdom that children where to apprentice a different race for five years and decide if they wish to finish their last two years or chose a different teacher.

The age for this ceremony started at age twelve and thirteen. The ceremony was called the Realms, I was to partake this year as I had reached thirteen.
I was so scared to see what teacher I was to be sent too.

I stood there in a peasant robe the color of grey, and wore a simple white dress. I stood in a line with maybe; two hundred other children of different races and cultures.
