Narrative Writing

Harry Potter- Darkness vs teenagers

In class we have been doing some fairy tail narrative writing, we either got to do a fairytail legend or myth, I chose Harry Potter.
But there is a plot twist with our writing, we are taking the story's and changing it and making it into something of our own.

Here's what I have started writing so far:

It was one stormy night and 3 friends were just having look around the school there names were Zak, Krissi, and Acea, they didn't even know how dark it actually was until they saw they walked around and went into an unlocked room with Windows all around it.

That's when they soon realised how late it actually was, so they decided to go home but what they didn't know is that someone was watching them… Following them… Hunting them…
