“Because you don’t notice the light without a bit of shadow. Everything has both dark and light. You have to play with it till you get it exactly right.”

–Libba Bray, A Great and Terrible Beauty

The shadows in the light and the light in darkness have become sentient, like little demona floating around where they don’t belong. You’ve started to notice shadows moving on their own and orbs of light floating around in the dark. You thought you were seeing things, finally losing your mind, but everyone morning when you wake up, something is missing, or moved, or upside down. It couldn’t just be in your imagination. So one night you set a trap.
