Thou shalt not deny us cookies before dinnertime!Note: while this is inspired by 's Woona illustrations, it is not based on, and in fact pre-dates by a few months, the Nightmare Moon Woona in Moonstuck. It also has nothing to do with Nyx/Past Sins. Thanks!
(If Tumblr would tell me the exact date of a post, I could tell you whether it predates Moonstuck altogether or not- they certainly occurred in roughly the same month
