From publisher blurb:
The Tocarra are a winged race similar in appearance to gargoyles, though they are not as fearsome, monstrous or primitive as gargoyles proper.The Tocarra have a great degree of sexual dimorphism with the males trading the power of flight for greater strength and tenacity as warriors and protectors and the females trading combat prowess for greater flight and the ability to explore deeper into the mysterious undersides of the floating landscape. The Tocarra are formed into large tribes and live a nomadic existence, following the seasons, plants and animals from one rocky island or landmass to the next in a great and constant migration, clashing with other tribes and increasingly with the colonists and explorers of the great powers as they move across the world.
