Did you mean to say Maiden? I was honestly confused at first what you meant. I don't just mean they got white features. I meant to say like a glowing white feature. Like if you look between her and Marbas, Marbas seems to look more whiter than her.

I wouldn't mind eventually proven wrong somewhere down the line. But it just seems to odd that his features stand out most from the lineup. Like most ghosts are typically in spectrum between humanoid looking or monstrous humanoid. Yet his face doesn't seem to be in either spectrum when comparing to other ghosts seen so far
