It can be said that Heaven is a great place, right? Sure, if you don't mind constant agitation and countless jobs. There're always things to be done but no real point in doing any of them. That can be said of anything, though, but doing something worth something is better than doing nothing for nothing. That's how I met Castiel.
Angels are always bound together and share the same goals. Some become skewed and turn to Lucifer's side and others fit to the 'good side' and some others fix somewhere in the middle. Castiel's side was just that, in the middle. For his living, he worked with humans instead of on behalf of them. It was something I didn't quite understand until I grew bored of just being an angel and wanted to see what exactly everyone was always whispering in scorn about. How could an angel work with humans? Or even more, lose their angel powers for them? If we fast track this, or even rewind this depending on how you look at it, similar things occur to me. Though for me it doesn't even involve losing my power for humans but because of them does that happen. This timeline neither fits as a before or an after, but a mix of the two. One came before the other, but the effects occur because of the past that ends up being a future.
For now, we'll stick to our current timeline, the learning of humans is difficult and simple at the same time to understand. Many have simple wants, simple needs and yet are always wanting more of whatever that need or want is. It changes from objects to people, personal goals or even to things like ideas. Expansion of such things is ever important and always changing. The majority of angels find humans about as interesting as ants. They occasionally cause problems but are generally small and unimportant and, if not messed with too much, generally don't cause annoyance. And then there are people like Castiel, whom try and persistently learn about their simple ways of life. The general education of an angel is usually limited on human information, though I've learned a great deal through radio and just generally know things about anything there is to know about anything at all. So learning more about human life was simple enough. I particularly found Egypt to be the most interesting, or any place where people created structures for some purpose they deemed larger than themselves. Places like Egypt were particularly interesting to me just for how they cared for things. Buildings were constructed with both detail and symmetry, each block cut a certain measurement and then placed in an arrangement that made the entire structure sound, but by creating internal structures within it, sections could just collapse while the outside main structure would never alter. It was an odd cycle, civilizations constant shift from one thing to the next, constant change of beliefs and feelings. The only thing that didn't change was structures, monuments, things that by some magic, withstood time and had more created all around the planet. The types of items they held, too, were interesting. Details put in, materials, the work and dedication needed to create such things was vast. That is why I began my own small collection of such things, first using books as well as collecting them and then sending Castiel information about things of interest. Not only did this further my liking for the culture, but my eventual visitation of it as well. At first I stayed more hands off, preferring to figure out how exactly everything from their world worked. I could care less how things worked in mine, it was bland in comparison and therefore was of no interest. I found it most interesting especially, of those that viewed it as the grandest of places when it indeed was not. It was confusing to me, but I took it as being something that only they truly understood to be true because they'd never been. Much as how I, having never been to theirs found it interesting as well.
It seemed to me that Castiel, however, had more than just an interest in humans but a want to be like them. He'd said once that he'd wanted to see what their world was really like from their eyes and learn to think the way that they did, to be able to solve our problems better, perhaps, with their techniques. It seemed somewhat insane, and everyone had objected. Due to this, all angels thereon had a dislike for him, stating that he'd betrayed Heaven and his right to be an angel.
Due to his descent into human life, he did gain years of experience ranging from their ways of fighting, views about Heaven, Hell, and everything else, to how they occupied their time such as the writing of books. Books have been a part of angel history, too but at least not in the same extent of that of humans. We have one scribe, they have millions.
Years past before we ever heard from him again, and at some point, the boredom got too much so guess who decided to take a trip themselves? That would be me. And the first stop? Egypt. Why? Because there were so many cool things I wanted to collect. Yes, collection of objects seems like an odd reason, but it was a learned habit. Humans seemed to mainly enjoy one type of activity, the acquisition of items. To me, that seemed great because in Heaven, nothing you own belongs to you. You're not allowed to own anything. You're given items but in no way are they yours. Therefore, collecting items became my most favorite activity. Sadly, Castiel had never been anywhere except for the United States, and knew about Egypt only through some brochure that he found in some motel. This made my knowledge of the place limited and relying on humans wasn't something I wanted to do just yet.
