Protagonistreader Stories

This is a rewrite of A World of Pure Imagination, though rather than it being every AU x the Reader, this has a sole focus on Error. My writing in this will be a lot more polished than it used to be, so I'm hoping it gains some traction! Thanks for all of your support!

And demons know as "Horsemen of the Apocalypse" began to wander around the world and kill the remaining humans. In response to the decline of human population and the threat of demons and vampires. Magical organizations are created all around the world.
