The woods near town is considered dangerous by the village 
The woods can alter anyone who comes in
Fae live in the woods
Giving a fae your name is the same as giving them power
Iron hurts fae
To trade with fae all you have to do is give them what they want and they'll give you back what you asked for, but if you try to trick them into a deal them they will seek revenge 
Saying thank you to a fae will allow them to take a favor from you in return
