"Apparently Ziatoch and the remaining Beasts are at open war with each other," R.D. said. "Gouki's laid siege to Shayol Ghul, so when the Dragon Tribes left Antarctica after I defeated Sheena, they had to take the long way around to get to Japan."
He explained that somewhere in Japan was a location called the Gray Mountain, where some extremely powerful and extremely gutsy warriors lived, and that the dragons planned on making an alliance with them, since Juno's old army had been decimated in Antarctica. "Things are made further complicated, though, by the fact that Juno's gone missing. They have no idea where he went, so Relayia sent another dragon out to Kattelox, because one of the Pillars of Dawn is there."
