It just dawned at me ....

Chatoyance is .. pegasister, at least formally. Hmm, can unicorn be pegasus at the same time? It seems yes, you just need to cast this spell about wings on yourself.

Also, because I prefer modern anarchy as frame of reference - my favorite Celestia is not classical ruler/power figure. She might be most powerful synthetic being in whole Equestria (when it comes to daytime and Sun) - but her power actually comes (or may be even circulates, not just one-way flow) from nearly all ponykind. So, she uses their unique energy for doing something ordinary ponies even assembled will find too hard and unfun to perform daily - yet she also feels a lot of emphatic/telepathic brief sliding connection with anypony - from nearest to most far away, both in distance and experience. So, is Luna specialized in night times, Cadance - in most advanced forms of love.. and Twilight in ...more deep and systematic than ever understanding of what it takes and gives to be friend? Yes, non-canon, but canon was written by humans, and has too many subconscious biases from society I actually have reasons to dislike and even fear ....
