User blog comment:FairyRaven/Fairy Tail Chapter 329: Seven Dragons, Review and Commentary/@comment-7505640-20130501071155

This chapter makes me more certain that the Anime's "Key of the Starry Sky" arc is canon because I don't think Cobra slipped a knife on his right eye in his prison. And now I wonder about which dragon will fight which dragon slayer...

Great job for someone in this wiki that has predicted this chapter's story.
