The Fae
Each fae has it's own set of evidence, though all evidence overlaps in some way. For this reason you'll need all three pieces of evidence to truly know which fae you're dealing with. That said, each fae has a rare chance of doing it's unique ability, which can out it if you can figure that out (the game lore makes this fairly easy to figure out if you come across said ability). All fae species have little elements about them that if spotted by a keen eye, will give away that fae. Also, among each species, fae can differ further in behavior. One Cold Rider might be more or less aggressive than another. Our goal is to have at least 10 fae by release, though twice as many would be a potential future goal.
So as not to give too much away publicly, I'm only going to list the names of the current fae here:
The Boogey Man (In the game currently)
Spring Heeled Jack (In the game currently)
The Cold Rider (In the game currently)
The Crone (In the game currently)
The Judge (In the game currently)
Madder
The Veiled
