Exile...

An orphan named Zane and his half-sister Daysja meet another orphan named Kevin and a kid named Damien when they all enroll into the boarding school, Asheville High. Since then, they've been sent to another world called Exile, learned about an evil plot to take over Earth, and learned things they never would have guessed about their parents. Their four lives have been intertwined since before they were born, and they must use powers that they were bestowed at birth to defeat the powerful evil that threatens their entire planet.
