### Summary
While the narrative continues to feature heartwarming moments centered on Leslie's growing friendship with Selis, this period of tranquility is shattered by a major political revelation. The central focus shifts to the imperial succession crisis, clarifying Empress Dowager Medea's long-held ambitions. It is heavily implied that Prince Arendo is not, as was believed, Emperor Pistore's son, but is actually Pistore's younger half-brother and Medea's own child with the late former emperor. This bombshell suggests Medea orchestrated a "baby swap," likely disposing of Pistore's true heir to position her own son in the line of succession, thus explaining her obsessive drive to see him crowned. Astute characters like Duke Salvator and his son Cyran are shown quickly grasping the gravity of this conspiracy. Amidst the high-stakes political drama, significant foreshadowing suggests Leslie's new friend Selis will play a crucial future role, with her apparent knowledge of herbs positioning her as a potential key to curing the spreading "ephialtis" plague. The chapter masterfully juxtaposes adolescent normalcy with explosive court intrigue, confirming the fragility of the recent peace.
