There are seven 'Representatives' from seven different countries around the world; France, the UK, Japan, Norway, Canada, Africa, Australia. They travel around to each country, transferring to a Wizardry school in that country. This year, they're going to Hogwarts in the UK. It's all very well; you're famous and respected, but not everybody likes you. The Representatives are stuck with each other for life- literally. Because if one of them dies, all of them die.
