Alright this was an amazing chapter in my books, but it obviously raised hundreds of questions, but.....after doing some thinking. and talking with Rag, I agree with him on the fact that, the Eclipse Gate is a portal to the Dragon's dimension, simply because it's ridiculous to think that 10,000 Dragon's are simply hiding around the planet, others would have found them by now.
Also....I have a feeling Minerva is behind most of the chaos thats going on, why else would Rogue kill Sting? Why else would Lucy suddenly want to close the gates? Other than the two of them having been massively manipulated by an outside force who would want revenge on Sting (for surrendering), and Lucy (to make everyone turn on her and blame her for the destruction of their world)
