Okay. Here's the backstory of this pony I created. (ahem)
I believe that there are most artists who make these wonderful MLP artwork on both FurAffinity and InkBunny. Some might believe that the anthro versions of the female MLP characters are pretty sexy. Of course, most of the ponies would understand that Heaven and Hell are somewhat of afterlife worlds. Does Lauren Faust believe in that kind of stuff?
Within that pony exterior, Religion was an Equestrian Pony in his past life. Because he was born with powers that no one knows of, mostly because of Heaven and Hell themselves, literally. Born from an angel and a demon that no one has ever heard of, Religion was casted out from Equestria because they didn't believe in that kind of stuff. He didn't understand how to use Holy and Demonic powers well, as he knew they would be disasters to every pony and alicorn. It is within his blood to find help from someone who can understand him, of course, his sister Avalia was the only family he ever had, ever since they were kids. She did not know what had happened that day on Religion's exile.
Since he was a little pony, he had quite a knack to understand the world out of Equestria some more. Of course, if you consider that his father is an angel pony, and that his Mom is a demon pony. Which some of you would think so.
Anyways, it wasn't long before Religion began to study about the Seracorns, that he discovered that his sister is one of them, and that he found out that he isn't related to her all these years. He was afraid that he didn't get a Cutie Mark on him, because he knew that he would learn both right and wrong.
Just like that, he was forced to leave Equestria for good, and never set foot here again, because no one knew that he was a hybrid, and that he wasn't fit to be anything to anyone. Having to leave and head to Nephilim Falls where he will start his life there in order for people to get to know him better, Religion wanted to be respected by many. It wasn't long until Danny met him, though. He taught the pony some stuff about Heaven and Hell.
When he discovered that Avalia wanted to learn more of Heaven and Hell, he set out on a path to truly discover who he really is inside. Not knowing when or if he'll ever be a brother to her again. As he began to understand that he knows about his pony inheritage, Religion began to become friends with Danny. There, Danny would give the pony anything he wanted, much to Gill's jealousy.
By studying about angels, fallen angels and demons, Religion began to understand that he is a different type of pony, from the normal ponies and alicorns. After studying to be something more, one thought came to his mind...is he ready to accept who he is?
