Traitors of reality

What would happen if 3 girls, young witches, from hogwarts find a time turner and go into the future; into the maze. Do they cause trouble or find a way out....

I don't own anything except Brodie, Tessa and Kylie. All the plot and Harry potter characters are owned by J.K. Rowling and the maze runner characters are owned by James Dashner.
Maze runner- It's only the characters with new background stories and not the plot.
