You did it, didn't you? You picked up a Portkey that brought you here. Welcome to The Portkey, home of all Harry Potter fanfiction written and created here.
I started reading Harry Potter five months after watching the first movie. Several months later, and many many fanfictions away, I continued to read the books over and over again, learning everything I could about this series. Harry Potter isn't a series that is to be taken lightly while writing, as it is so in depth and full of background and history in the wizarding world.
I present to you, stories called Improbable Works. Stories that will change the way you look at Harry Potter stories, with humor, adventure, and every so often; a Monty Python reference. Cheers.
