Lonely Luci, and oh yeah, Dean’s an angel

The archangel’s claimed to be entirely pure or the perfect first creation, at least they were foretold as such. There was some speculation that the archangels may not have been the first angels after all, that maybe there was someone made before them that God had made in his first attempts to create.It just so happens that the speculation was correct, and in fact there was a more ancient angel then the archangels. After an odd encounter with Lucifer during the end-times, after Michael and Lucifer were thrown into the cage, after Castiel cracked open Purgatory and “died”, releasing Leviathans, in a last ditch effort Sam and Dean decide to do some more digging and happen to find in an old legend saying there was supposedly a book about angelic speculation and history buried beneath most of the other lore that could give them answers. They encounter many familiar faces on their quest to find the book, and once they do they eventually discover that the key to finding this angel and kicking some demonic (and angelic) ass may have been in front of them this entire time, and they aren’t just talking about the Leviathans.
