To maintain the city and fight for sky dominance, elite multi-species dragon-riders known as Dragonators harvest amber from surface lava pools amidst dangerous Warp Winds and factional warfare. Amidst this conflict, a team of protagonists navigates political intrigue and perilous surface missions to contact their mother and survivors on an orbital space station, and to discover a legendary surface oasis holding the key to Earth's rebirth.
