User blog comment:Belanderanime/Question about the 3 FUTURES, 10 000 dragons PLEASE HELP!!!!/@comment-7418318-20130707183624

In the first timeline the 10.000 Dragons came through the Eclipse Gate. Future Lucy just didn't know where they came from, because she was imprisoned and thus never learned the origin of the Dragon. During the Dragon attack she was knocked unconscious. When she woke up she somehow got out of her cell, made her way to the Eclipse Gate and fiddled around with it till she somehow managed to travel back in time.

Due to her presence time was altered and the Gate was either closed or prevented from opening in the first place, thus creating a second timeline without the 10.000 Dragons. Here, at some unknown point of time, Acnologia devestated the world and wiped out most of mankind.

In response to this Future Rogue developed Dragon Manipulation Magic, but due to Acnologia's strength he couldn't use that magic directly on the Dragon King, so Rogue traveled back seven years into his past.

Once there he convinced Hisui to open the gate at the point of time where it would go out of controll to let the Dragons of the past in, so he could take conroll of them. Once he had that army of Dragons under his controll, he intended to make them kill Acnologia and use them to dominate the world himself.
