Yonna wields magical powers enabling her to craft creatures from flower petals. These abilities led to persecution and ostracism for her and her older brother Stan by their village community from childhood onward. The persecution left them orphaned and ultimately forced into exile.

They found refuge in an isolated fortress, living without neighbors or outside contact. Stan became Yonna's self-appointed protector, enforcing strict isolation to shield her. His protectiveness intensified over time, confining Yonna as a virtual prisoner within the fortress walls.

Yonna initially accepted this seclusion as her own choice, shaped by past trauma and mistreatment. Her perspective changed when agents from the governing Monarchy arrived, seeking to recruit her for her powers. This intrusion shattered her acceptance, especially when Stan reacted with lethal violence against one agent.

Witnessing her brother's extreme act ignited Yonna's transformation. She realized her deep desire for freedom beyond the fortress. Ultimately, she chose to depart the solitary fortress with the young agent Galda, not to serve the Monarchy, but to claim her own path and autonomy. This decision marked her shift from enduring isolation to actively pursuing self-determination.
