So the gryphons are big, and boy are they gaudy.
Their builds come in thick, thicker and thickest, with immense strength behind their limbs and a real scary bite to back it up. Typical distinctions to look for are the feathered ‘manes’ which range from a top half to full neck, fluff stopping at the heel/elbow, paw-claw hybrid feet, and the dual layer tail.
They are proud beasts, easily offended and quick to snap you for it. Not to say they can’t be diplomatic mind you, but really who’d risk it.
