Storm Hawks is set in a fictional world called Atmos, a largely mountainous world consisting of scattered masses known as terras. Directly below the terras is the Wastelands, the most dangerous place on Atmos, with its infernal fires and wicked creatures. Because of the geography, travel is mostly dependent on flight. The technology of Atmos is based around energy-generating crystals, used to power the various devices in the series. Patrolling the skies of Atmos are the Squadrons, all led by a Sky Knight, groups of warriors who pilot motorcycle-like vehicles called Skimmers that can semi-transform into flying machines. These warriors are loosely managed by the Sky Knight Council.
