Oscar brushes it off and is fascinated by a mysterious bloodstain on a box containing a chain inscribed with "Aeti." Another box falls to the ground, revealing a blue orb, which he picks up.

Suddenly, he realizes he has been sent back in time and claims to be from the year 654, four hundred years in the future. He visits a younger Tinasha in the neighboring town and asks her to send him back to his time. However, Tinasha explains that time travel is impossible. They decide he can stay with her while she searches for a solution. Oscar, noticing that Tinasha is only thirteen, offers to protect her and reveals his familiarity with her morning habits.

The story delves into Tinasha's determination to serve her kingdom despite potential dangers. Oscar enjoys her tea and expresses his desire to save her from a future tragedy. They discuss Oscar's unique sword, Akashia of Farsas, and Tinasha's curiosity about its complex curses and blessings.

Oscar suggests training Tinasha in swordsmanship to protect her in the future and reaffirms his intention to stay by her side. As Tinasha learns more about her future self and Oscar's royal lineage, their bond deepens. Tinasha's relationship with Lanak comes up, revealing tension between her trust in him and Oscar's warnings.

When Tinasha plans to access the treasury with Lanak's help, Oscar advises caution. Tinasha resists, emphasizing Lanak's importance to her. In a touching moment, Oscar comforts Tinasha, assuring her she won't be alone in the future. Tinasha manages to break the treasury's protective spell, allowing Oscar to retrieve a blue orb.
