The Element Holders

Solis was found unconscious in the middle of the woods. When she awoke they discovered she had amnesia. The only thing she was able to remember was her name. The amnesia's not all that's weird though. She knows the old legends of the Element holders. But she swears she's never read them in her life. But things go even more weird when teens dressed like it's the 18th century show up, who seem to know her. What's going on?
