User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-75.164.255.132-20140503193840


 * Spoilers***** Actually, Zeref remembered being killed by Natsu 400 years ago before he turned immortal. In Natsu's first world Zeref had turned immortal, so he traveled back in time 400 years to kill him. Zeref would have to exist for Acnologia (a dragon he created) to destroy Tenroujima so that Fairy Tail would spend 7 years in a perserved state, so that the guild's rank would decay, so that they would have to join the Grand Magic Games, so that time travel would be possible for Natsu, so that Natsu could kill Zeref before. Its a confusing plot... but in the end Zeref knew at some point Natsu would be strong enough to defeat him, and he wanted to be defeated which was why he was dissapointed he couldn't defeat him at Tenroujima. ---This is speculation at the Grand Magic Games plot... when they said Acnologia was created by Zeref and the castle's intent was to travel back in tie 400 years. *****Spoilers*****
