Christina Rey Holden, the thirteenth princess of the declining Kingdom of Estgloria, faced exile to Shina Dark Island as a sacrificial offering. Queen Catherine S. Langton orchestrated this politically motivated removal from court, fueled by hatred for Christina’s mother. Years of systematic poisoning by the Queen left Christina with enduring health complications and physical frailty. She secretly countered toxins using medicinal herb knowledge, though residual effects weakened her constitution.

Initially plagued by self-perceived inadequacy and uselessness, Christina transformed after Exoda C. Claw, Shina Dark’s sovereign, designated her as Blue Moon Princess—one of the Twin Moon Princesses symbolically leading the island. She uncovered her strategic aptitude, consistently defeating opponents like Exoda in chess through foresight and tactical ingenuity. This analytical prowess extended to military strategy, where she served effectively as a battlefield commander.

Christina developed a respectful dynamic with Galett Fey Sowauge, the Green Moon Princess and fellow exile from the Vansable Empire. Cultural and political differences sparked early friction, but shared responsibilities forged mutual reliance. Christina regarded Galett as both a trusted friend and romantic rival due to their mutual affection for Exoda, stemming from his compassionate treatment.

Her emotional journey centered on overcoming abandonment trauma and seeking belonging. Exoda’s kindness in offering refuge and purpose cemented her loyalty to Shina Dark’s ideals. Through governance challenges and confronting threats from her homeland, her resilience grew despite lingering vulnerabilities.
