Three things:

A) This is Two Rooks: /volume-i/ Get educated ;)

B) Personal fiction doesn't really belong on a fanfiction cite, you know?

C) I really wish this was more complete than less than 300 words. I think this could be a fun story if you finished it.

Or, I guess 4 things D) This reminds me of this one book series I read as a kid: Avalon (or something). It was about three girls who found stones that gave them powers. Of course, they also had animal companions, but what can you expect from a book for girls?

Maybe an author's note would be nice too? To explain what your intentions for the story are? Then we can give you some better feed back then "Tell us more please!" Like I said before, it seems like you could take it somewhere, so take it where it leads you! :D

It's an okay idea, but try adding A LOT more detail!
