Aglolof

Aglolof are large, winged creatures that live at extremely high altitudes, often above the clouds. They have a long, thin body and enormous wings, attracting many would-be riders to attempt to climb up to their lair, but few survive the journey, both because of the difficulty of their ascent and their host's violent reactions to their presence. They feed on insects and small mammals, and their excrement is often used by shoemakers to strengthen leather. They are born in clutches of 15-17 eggs, and will lash out at any perceived threat to their young.
