Predator: A Handful of Villains

This book will need a whole bunch of people out to get other people. Predators, in some literal senses.
So far, of our major background disasters, we have the idea that it's split between below the earth, on the earth, and above the earth. Also one is associated with the Fae Court, and another has to do with vampires/werewolves. Not sure what #3 will be yet.
Also the Mentor needs his own personal villain who's not quite a world ender but is certainly making things difficult. That's for not me to decide.
The Teacher will need her own antagonist, though. The Mentor can serve for a bit, but there should be someone else who's making her life worse. Probably the school administrator/principal (ask teacher friend for which could potentially cause more problems) who is trying to hedge her out. Or, more likely, a supposed friend in the department who is doing it less to protect secrets and more just to be mean.
