A long time ago there was people who were different, they had powers. They were criticized and unwanted by society. People who didn't have powers decided to end them, and they did, or so they thought. The survivors of this magicians, as they were called, move to and island, where they built a passthrough to another world that they created. They live there for years but now they need someone powerful, someone who once used to be of the human world to be the one to guide their magic and their world. In this world they were unwanted. In this world when a child was born with magic is unwanted and mistreated. When a magic child is born is usually disowned and thrown away.
