A clash in the sky! The fate of the world at stake!

''Grand line, off the coast of Jaya. approximately four years before Luffy became a pirate. a small boat is in the process of being unloaded from a much larger one. on the deck of the large vessel, Nova Blade is talking to Monkey D Dragon''

Dragon: You're ready then? It should be passing at any second.

Nova jumps into the smaller boat

Nova: I'm ready.Shouldn't take long

Dragon: Be careful. This island isn't known to any of us. And good luck!

''The large vessel sails off. Nova Blade moves his own small vessel to a specific point, then waits. A short while after that, the ocean bulges, and a knock up stream blows his boat skyward.''
