So cutethere needs to be an episode where Eclipsa, Moon, Star, Marco, and even glossyrac and the high magic commission cross paths with the past queens of mewni's ghosts. I can see the drama endured with Festivia realizing she and her family were lied to for so long, and solaria realizing her daughter loved a monster and had a child with him, ending with Star telling off some of her family members (mainly festivia and cressentia) and solaria that they made things worse for mewni.maybe even learn more about solaria's death. I still have my suspicions especially when shastican being engaged to eclipsa since Solaria didn't see kings as anything but throne candy.if all 13 of them were shown in the book of spells its likely they're the more important queens and we'll most likely see them in spirit form aiding star and co in the final battle (at least that's my guess)beautiful work btw, sorry about the rant
