Where am I?

So basically, Emyr can Au travel, but sometimes his power backlashes, and they travel to an Au, he sometimes doesn't know about or just completely forgot, so this story is about the times that said power backlashes and they try to figure out the Au she's in at the moment, this is also my first story, and I have no clue what to write exactly. But I hope people like this cause I don't think anyone else ships Valgrace plus Percy, I think their ship name would be Valgrason or something. But anyways, enjoy.
