My site exists in an Alt Universe where earth has always been openly inhabited by the supernatural. They exist openly among humans - most of them do anyway. I've been building an NPC sort of bestiary to give people an idea of the various beasties they can use to enhance their threads and plots.
Some of the fauna on the list are the leucrota - weird hybrid hyena-horse-wolf kind of thing. Griffins exist, phoenixes, wendigo, valravens etc.
Flora wise we've got things like mandrake and Peridexion, which is a kind of tree that repels dragons because it smells awful to them and is pretty toxic but it attracts doves and other birds heavily because they like the fruit.
So in that kind of vein, what sort of things would you like to encounter as a player?
