Sky bison, also known flying bison or air bison are gigantic six legged creatures, weighing up to ten tons when fully grown. They are covered in shaggy white fur with a brown line that runs from the end of their Manatee like tail ending in a large arrow on their foreheads. Despite their size Sky Bison are gentle, herbivorous creatures that rarely attack unprovoked. They do however fiercely defend their young and (if tamed) their masters with both their physical strength and their elemental mastery over air. Sky bison also have the ability to float through air with ease and grace, without the use of wings or propulsion as if swimming through the sky. A fully grown sky bison can carry up to 15 medium sized creatures on its back, however without an appropriate saddle the journey will not be very comfortable.
