Isida Kep'tukari ran a PBP game here called Vasorn: World Under Dragonfire. I think the idea was similar to Reign of Fire. The dragons ruled the skies, and everyone humanoid had retreated to the drow caverns where they formed a shaky alliance trying to take back the surface.
I'd be tempted to handle it as a new land ruled by dragons that the humans are contesting. Think the European conquest of America, but the natives have dragon protectors. Or as a Dragonstar takeoff. A gigantic colony ship full of dragon eggs crashes. The ship's programming speeds up the hatching mode, and uses the last of its temporal adjuster to bring a round hundred hatchlings to adult or older to act as protectors. The Hundred become the rulers of a new, rapidly expanding dragon realm that spreads faster than the news.
