Still on a helltaker kick.. fascination?
Anyway.
I've seen a few people do Abaddon OC's but most of them make her a demon or fallen angel... thats fine, she can be depicted as such, but most the stuff I find online describe her as an angel. Still serveing god as a destructive force. So, would she not be an angel still?
I've also found a lack of reason given for her falling, such as Lucifer Rebelled. Beelzebub joined Lucifer. Belphagor is stated to have not helped ether side, slothful, and cast out. But Abaddon? No real reason just places saying she is a demon... So with out a reason I'm going to belive she is an angel.
That being said, I find it funny that there is conflicting evidence saying she is a demon. So why not have this angel be corrupted? She spent so long in the abys that the abys claimed her as its own angel. She still serves god, so didn't fall, but is corrupted and thus is mistaken as an demon.

Ill have a babysitter comic page out before next week, sunday the latest, but I'm slow and lazy.. same thing.
