New fic of yours! Cool!
This is quite an original fic, with pretty good decription, althoguh the apperance of characters and such could have been expanded a bit. Arista seems like a nice main character, but you could show her personality more -- I know no one does that in the first chapter, so ti doesn't matter anyway. Besides, the whole thing with Chikorita/ Meganium gives us quiate an interesting hint.
This fic is good. Don't give it up!
