So I did some sketches of the past versions of Hallow and Orion, I also have a short story up in the book called "my OCs and stuff" about specifically their past life if anyone's interested.

Yes Hallow had boobs in his past form, still male though.
Was  also known as the Prince of the Dead.

Literally the opposite of a angel.
Was outcasted by his family as a kid and vowed to get vengeance.
