### Summary
The central conflict has escalated into a high-stakes political conspiracy orchestrated by the Dowager Empress Medea. She is manipulating the imprisoned and delusional Ellie Speràdo, using her as a pawn to acquire a sealed box containing a divine plague. Medea's apparent goal is to leverage the threat of a pandemic to install her favored candidate, Crown Prince Arendo, on the throne. This scheme has forced a morally ambiguous decision upon Duchess Azela Salvator, who is concealing a dangerous truth from her adopted daughter, Leslie. A ritual connected to the box has been fatal to past participants, raising the disturbing possibility that Leslie was adopted not only for her safety but to serve as a countermeasure or even a sacrifice, echoing the very trauma she escaped. This secrecy has created a new, internal conflict, as the Duchess's plan to protect the empire risks a profound betrayal of Leslie's trust. Amidst this tension, there is speculation that Leslie's unique shadow magic, which now exhibits its own consciousness, may be the key to handling the artifact without succumbing to its deadly effects, though her mother's choice to keep her in the dark is seen as a grave miscalculation.
