@mageexia @Velsy It took some digging on my part, but I did manage to find the source. It's just some random person's
original character on deviantart it seems.
Probably kind of a dick move taking stuff from on there without even sourcing it? Not because it belongs to some random scrub, mind you. I mean look at where we are, violating copyrights all day every day over here, and for all I know that username on DA belongs to one of the group members, that's just "whatever" either way. The dick move is making me dig through reverse image searches for something like this since I initially figured it was from a series the group worked on but didn't see anything that looked right there either. It kind of looks like there's a... marking in the bottom right even on the DA one but I can't read that shit. Maybe the LN on the bottom left here is for their name too, but that's useless for searching too.
