You are very superstitious and believe in all sorts of mythical creatures. You've even had proof a couple times. You are very lonely and people call you weird and they laugh and they tease. Even your family does sometimes. You are sick of it. One day you see a birthmark on you that you never noticed. It's in the shape of an ''X''. You think it's really cool.

Now, the ghost clan are looking for humans with the ''X'' birthmark. Their targets. The ghosts' goal is to track down and follow a human with the ''X'' so then they could haunt and kill them, turning them into ghosts to join their clan. But now one thing the marked humans don't know that the ghosts do is that the marked humans are the most powerful humans alive with strange powers that nobody knows of. That is why the ghost clan need them.
