The Alpha trolls and the Beta trolls came here from a distant land, intent on stealing the magic the eight kids posessed. But the Beta trolls soon came to appreciate the ways of the kids, even befriending four of them.
The Beta urged the Alpha trolls to abandon their plans. When they refused, the Beta trolls alerted us to the trolls' intentions.
The Beta trolls returned to a peaceful Beforus, and the Alpha trolls was sent back to a corrupted Alternia for their crimes, an exact revert. But it appears they have found a way to escape.
