Quinn was born in a small village, far away from most of the other villages. They were the quiet kid and thus, it was difficult for him to be with the other kids around although he wasn't alone or isolated. They had friends, sure, but they never really though much about them.
They'd go to the river, catch bugs or make pranks, but they never had a best friend or anyone they would consider a close friend.

Once their horns, and thus, their powers, started to appear, Quinn naturally began to experiment with them.

They quickly discovered that they could make objects levitate. They would try to make stones branches fly and they loved training their levitation powers! This made pranks and games much more fun.
They were suddently swarmed by the other kids, getting requests to levitate all sorts of objects. But that kind of attention was burning the young Quinn out and they started to isolate themselves. Despite expressing their frustation to their friends, the kids seemed to treat Quinn like a circus animal more than a friend. 

Quinns teenagehood was... troubled. They would use their telekinesis to mess with people on an everyday basis.
They'd hide books, tools and clothes away from the people who were looking for them.
They'd throw plates full of food to the farm animals and laugh about it.
They'd take things from others peoples hands and hit them with it.
They'd break other peoples things. They'd steal.

Eventually enough was enough and while their poor mother tried doing the best she could do for them, she had to make the harsh decision to send Quinn away.
So they went.

Quinn's Cosmic Curiosities is located in the middle on nowhere, atop a cliff, but people have seen it at the beach or inside a cave. Hmm That's weird.
