Thank you very much. I also think that time travel is the only real possibility with the death of Layla and the dissaperence of the Dragons both being in the year X777 it's a pretty big coincidence that the day Layla died is the same day the dragons "dissapered". It could also be another reason that when Natsu first joind the guild he didn't know that much about modern society. The 12 keys all being in Fiore that is a either a mystery or spelling mistake.
