Evolved from the common four-legged, two-winged dragons, the Reapers have gone through a drastic change in body structure in order to adapt to the high altitudes. Their back legs have shrunk so all the weight and strength is diverted to the front of the body. Their front legs are stronger and act as talons to grasp live prey. When not flying, the Reapers will walk on solid ground with their front legs/talons and the tips of their wings.
