Lucifer SPN²

Michael, Lucifer, Raphael, and Gabriel. Brothers archangels, but there was also a fifth: you. You were beautiful. Your appearance was magnificent, and your wings... the wings alone were worth it. They were snow-white, with a golden tint. You were the most beautiful in heaven. Lucifer (you called him Lucy) raised you from childhood; he taught you to fly, cleaned your feathers, and combed your wings. You were very close until one day... Lucifer fell and was locked in a cage in hell. After that, Michael raised you.
And then the Apocalypse happened, which meant Lucifer was free. You always kept a low profile, but when you heard about Castiel, the Seraphim of Paradise, you trusted him and began trying to somehow avoid the Apocalypse. You somehow found yourself caught in a ring of holy fire set up by demons, and within minutes, Lucifer stood before you. You simply looked at each other, unable to believe this meeting had happened.
