Fairy Tail : Apocalypse and Angels

Hello!

So, hi! To make things a bit straight, Kasu is my fictional character and I made him up long before I knew about Acnologia. To get best results and to understand who is who please finish all of Fairy Tail or it could get a bit confusing.

Have a great time! I'll try to update every week or twice but I have a busling life so it is hard.

So, here is the dragon history. If you think I missed any details please comment!

DRAGON HISTORY
So, long ago,a bit more than 400 yrs ago dragons ruled the earth. And an occasional human village or town had people. One of these was a town in which Zeref and his family lived. When both Natsu and Zeref where young children, the dragon war broke out. It was between letting humans grow more and live amonst them or to leave them in their status. Any way, during the war there was considerable damage and Zeref's younger brother (Natsu) and his parents died. Zeref was the only one left alive. Around the same time, dragon slaying magic was created. Now, the thing is a dragon slayer will never have the ability to slay dragons unless he takes the physical form of a dragon. And that was the fate of all dragon slayers. The most notoriuos was Acnologia. His parents that he loved dearly where killed by dragons, so he built an instant hate for all dragons. Ever since his parents died he became ruthless and cold-hearted and had no mercy to those suffering the same. He studied dragon slayer magic in order to destroy all dragons. When Acnologia started breaking out, Zeref started learning black magic in order to revive his brother. During his research he came acroos Akuma the Nature demon who placed the curse of contradiction. Every time he tries to do good, he does bad and when his intentions are bad they are good. Obviously he had no intentions of being bad. Also as a part of the curse of contradiction ment he was immortal and the more he loved life the more he'd steal away. So he revived Natsu as E.N.D in order to kill him. After that he went to Igneel to train as a dragon slayer. When war was breaking out, Zeref also created the eclipse. Anna-Sensei realised that humanity would be doomed. She created a book on how to activate the eclipse. It passed down from generations to Anna Hartfillia. She gathered all the dragon slayer kids to go to the future. (Gajeel,Sting, Rogue,Wendy, Natsu) To go to the future. All their dragon's spirits had been torn out by Acnologia. In order to keep themselves alive and to fight Acnologia later on they sneaked into the bodies of the slayers and went through the gate. Anna Hartfillia opened the eclipse but the kids scattered away. And Zeref met Mavis many years later and accidentally killed her with the curse of contradiction... But that is another story..
