You've Picked Me, Princess

Hi guys, before I do my description, I just want to say that I know this idea has been used a lot but I made this one much more epic. I couldn't resist writing this one and I just needed to get it out of my system. Also big thanks to brechtixncider aka Wynnie. Her convincing opinions built up 99% of this story. Now onto the description.
