Chapters (1)
Still needs a lot of work friend. But overall not too bad. Your dialogue seems a bit too simple and there are still quite a few spelling errors. Grammar needs more attention as well as use of words. This is just my personal preference but the way you had the seriousness of the beginning conversation between Star Swirl and The Oracle was great, but ruined at some of the jokes added into it
. Just watch what you add, sometimes there are things you don't need to put down. Just keep up the practice and you will get there! 
I really think that people need to move past the fact of there being grammar errors. Seriously, if you can understand it, then it shouldnt be docked for that. This story, has a good plot behind it.
I have now found TWO "7th element" fics within ONE page of each other on the "Recently Approved Stories" pages.
