I'm writing this story set after the events of Rainbow Rocks. It's follows two Ocs who are both magic users (one uses the element of fire and the other uses the element of darkness). The two of them are on the run from the person who gave them their magic and learn about the portal to Equestria at Canterlot High. Seeing it as a chance to escape for good they attempt to get it working while also trying to fend off others with similar powers to them who are trying to bring them back.

I'm struggling to come up with a name for the story as well as the character who uses darkness so I was wondering if anybody has any ideas about names.
