I'm still of the theory that Agatha is eventually going to change the way Sparkiness works on a fundamental level. The OG time portal at the beginning of the story is the Muse of Time/The Other pointing at Agatha while she's under the effects of the locket and saying "...like THAT!?"

My assumption is that Future Agatha is present on the other side of the portal, prepared to discard not just Queenhood but some greater part of herself that would bring her down to being "normal", like how she was when growing up with her Spark suppressed.
