When a mysterious mirror is found, a quest is issued for 13 demigods, 2 wizards and 2 Titanesses(and 1 willing mortal, thank you very much) to travel to the Scottish Highlands to merge with a group of 4 students at a local school. Their quest is for them to stop the worst enemy the heroes will ever face. There's a few difficulties though. The school is for wizarding, the event they are supposed to stop already happened in a different reality, and they have to go undercover, unable to reveal their godly bloodline or real identities. WARNING: There will be 1-3 OC's added to make the story flow better, but I promise there will be no OC outshining any already existing character. Augustine is really important, so please don't discard her as just a self insert or whatever. I'm gonna try writing this with the least amount of stereotypes possible, so if you like arrogant Harry, the Golden Trio claiming that the demigods are death eaters right off the bat, etc.., this isn't what you are looking for.
