i always think of castiel wings as a pure source of energy. they are not wings, not really, but a bright light, spouting from his back, lighting up the whole area around him with something that makes everyone shiver. they are like waves, never still, always moving, and sometimes parts of his wings explode, i don’t know, maybe when he is feeling too strongly but when they do, all you can see is colors, bright colors, some you don’t even have a name for, colors you have never seen on earth. his wings are beautiful and majestic, but also terrifying and dangerous, just like castiel himself.
