It exists because I made it exist, and I made it exist because I wanted it to exist. I was not going to find the exact type of story I was looking for unless I made it myself. It's unique because it's MY story, and not just in the sense of me making it, but many of the characters and events in it are things that I relate to, have been through, or I am going through.
I'm not trying to be deep of philosophical or anything, that's just pretty much it. I wanted a story I could relate to with characters that lived through situations and experiences, (or allegory of those situations and experiences) that I remembered going through but never got the media representation of, making me feel alone, like I was crazy, like I was over reacting, and after enough time like my experiences were a lie and maybe this was all in my head. I feel like if there are other kids and young adults going through that, having a story that touches on this issues to prove or help them understand they are not alone or crazy, then they would grow up a lot more happy and less scared than I did when I had no stories to help me through these things.
As for the 'magical' aspect in it, I just really like mythology and want to share that too with other people that like it or for other people to get interested in it.
