The parents of royal Otharian twins Darius and Dyla have been murdered; their cousin is stealing their throne, and they are falsely accused of murder. Their only choice is to flee to the forbidden and quarantined planet Earth, but it could turn out to be a one-way trip.
To return home, they must find an ancient crystal, that once belonged to Merlin, to power the return portal. When the twins stumble upon the location of the crystal, the local crime boss sends out his assassin to retrieve it. Can Darius and Dyla use their PSI powers to open the portal home and reclaim their throne before the assassin catches up to them?
