Okay but hear me out

So this is basic just fanfiction at this point, but what if instead of being fucking stupid, the royal family actually publicly revealed the truth about Amaryllis having been a homunculus and the origins of the prophecy, and lets pretend it actually manages to convince the majority of people, leaving only a small sect of religious fanatics, convinced that the kingdom is doomed by the darkness that has consumed the royal family, unless they bring back the light. This gives birth to Amaryllis' "final form" as a villainess: a religious symbol, revered as a savior (which she already supposedly was on a level, but somehow all the plot leads tied to her really were just dropped) that needs to be risen from the dead. The real fanatics accept that she was a homunculus and take it upon themselves to make new homunculi in her image and have the ultimate goal of overthrowing the royal family to purge the palace of the darkness.
Meanwhile the royal family gets to be tormented by the face of their enemy being the face of the daughter and sister that they loved and lost, back now to haunt them and destroy them for their incompetence.
