Monsters.
I've been reading a lot about _monsters_.
As I write two adventures for Monster of the Week, I'm realizing there's a reason they suggest you start with the monster and work from there....the number of monsters, mythological threats, and otherwise spooky entities living in my head is large, but the details on them are thin. This is how I spent tonight googling things like:
monsters that guarantee youth
pied piper
doppelganger
curiosity monster
