The lands of Avindron were once protected by an order of knights that rode on the backs of dragons. These dragon riders kept peace between the kingdoms, and for centuries this peace held. Then, some two hundred years ago, the order was destroyed from within. The Galra emperor Zarkon, along with a handful of defectors, led a joint attack on the rider's stronghold and the capital of Altea, destroying both the citadel and the city itself.
In the ensuing chaos, Princess Allura of Altea, along with her adviser Coran, managed to save three eggs from destruction. However, Altea was lost, and what remained of the riders were scattered and hunted. Allura was forced to flee, and has since been gathering allies to strike back against Emperor Zarkon before all of the remaining kingdoms are under his control. She now knows a fourth egg is in Zarkon's possession. Allura and her allies make a plan to rescue the egg before it can hatch for the Galra empire.
