You're sitting in the study hall, taking care of your homework and studying for the upcoming History of Magic test, when suddenly, someone appears in front of you, hanging upside down.

"Boo!" He shouts, as he hangs in the air like some sort of wild vampire. It's Lilia, your friend. He's very, very short... Maybe 5'3 at max, and he actually looks like a vampire. He's rumoured to be 700 years old, despite looking so young.
