What made you think he was a demon in the first place?
Perhaps the title is misleading. "Deceiver" is used frequently to represent the devil or his demons.
Could someone edit the identifiers part on the Creeping Deceiver card on redemption wiki as it has no human identifier on it? Unless I could do it but not sure how??
I do not use the Wiki, but I would think humans are not given an identifier in general. The presumption would be that all characters are human, unless they specify otherwise. Any characters that are demons or beasts should specify as such. I'm not sure if the wiki specifies an "animal" identifier that would be used for characters like Leviathan, though.
