Dear Children,
If you have any witcheries that you would like to explore, you are welcome to come to our school at Witch Academy, across from Wizardry Academy.This is a Top Secret school, only for children who are born into magic families.
We hope you accept this offer, for it's a one time offer, for the next time we send this letter, it'll be ten years from now.
See you at school witches,
Professor Cloud
