### Summary
The narrative takes a sharp turn as the disgraced and increasingly unhinged Marquis Speràdo becomes an unpredictable agent of chaos. He has stolen a highly dangerous box containing a partially awakened power or plague known as "Ephialtes." This act of reckless greed derails a meticulous plan orchestrated by the scheming Dowager Empress, Medea, who had apparently entrusted the box to Leslie's vengeful sister, Ellie. Now, the Marquis wanders through a public town with the unstable artifact, creating an immediate and volatile threat. This unforeseen development has thrown all factions' plans into disarray, with readers speculating that the Marquis's sheer idiocy might ironically sabotage the Empress's plot. Furthermore, many theorize that the Marquis himself, consumed by envy and delusion, perfectly fits the profile for the final sacrifice required to fully unleash Ephialtes, suggesting his reckless actions will lead directly to his own gruesome end and potentially trigger a catastrophe.
