Fallout: Equestria Resource

The fate of each of the mane 6 got my curiosity after I read Fallout Equestria. So, I've decided to make a side story about them during the events of the original, featuring one as the main protagonist. However, my main problem is that i am using a large amount of the same dialogue from the original Fallout Equestria in my story. I don't want any legal trouble or anything, but is there anyway i can contact Kkat and ask for permission (or something)?
This will be my first fanfic, and i will be open to critique. I plan to write this story in about 10 chapters or so. Wish me luck!

You generally don't have to ask for her permission to do this. You should just mention her at some point. But if you really want to, try the IRC chat.
