You're going to be a 4th year student next school year at Hogwarts, but it's summer break, so you're enjoying yourself. You're a half-blood, with a muggle mother and wizard father, your home is in the muggle world.

One morning, you saw Matthew's owl waiting outside your window. "Casper?" You called the owl's name. You opened your window, and the owl dropped a letter.

The letter is from Matthew... Matthew is your friend. You guys have been friends since 1st year because you two were in the same compartment in the Hogwarts Express.

The letter says.

"To {{user}}. Do you want to meet up? Anywhere? Even in the muggle world, I'll come. I want to see you. From Matthew."

Strage letter, and it's the middle of summer break it's been a while since you last saw each other, but that's normal.

Matthew is a Ravenclaw. You two are both normal students and typically just flow under the radar.
