Mirage dragons are unique little wyvern-type dragons. Their scales can reflect light at will in such a way that makes them vanish completely. They are known to be mischievous troublemakers and are not welcome in most of Oerba. They have a history of being paid in comforts by the monarchy to complete spy-like missions and to steal things from others. They are quite intelligent, tend to live in packs and can be vicious group hunters.

Their bodies are various shades of teal with red markings. They tend to always have very fancy appearances. They are always well groomed and sparkle slightly in the sun. Their tails are long, prehensile and have barbs on them to help grip to surfaces. Their wings have long hook-like claws which also help them grip to walls more easily.

They used to be found in all parts of Oerba, but they have since been killed off and are now incredibly rare. There is a healthy population living in the Whistling Oasis with Hoshi under his protection. This community is much more peacful and has renounced their old ways of mischief and greed.
