- Pied Piper sounds a lot like what Pan was doing in Once Upon a Time. That could be a good reference if you did that plot.
- I like the idea of some sort of possession.. demon/spirit/something. Makes you do things you don't want to do. XD
- Any type of amnesia that is maybe somehow contagious and there are certain steps applicable to each character to require getting their memory back.
- A type of bioterrorism or something that causes either permanent defects or marks on the surface. Could be another way of killing off characters in a cool way. :)
