Amidst a celestial journey, she is summoned back to the royal palace and coerced into an unwanted union with a neighboring realm. Stripped of her voice, her sole weapon, she clutches a starry gem and ventures forth in desolation. Through a dark forest teeming with monsters, she arrives in the neighboring Holy Sword Country of Red Ark. There, she encounters a prince with extraordinary abilities, bestowed upon him by the enigmatic Night King.
