For thousands of years, the House of Ammanon has ruled Primatia with justice. However, their alliance with the otherworldly Lystrians is changing their noble principles. The Lystrians, advanced and soulless entities, seek a fabled ore rumored to contain a substance capable of opening celestial gates. To mine this ore, they counsel the king to seize lands reputed to be rich in it and employ the crestlings, creatures with earth-shaping sonorous skills, to find it. In exchange for their help and for hiding their dark deeds, the Lystrians bestow wealth and power upon Primatia's king, ushering in an era of social division, avarice, and dread. As greed prevails, the world teeters on the brink of disaster.
Everia, a celestial realm in the Fifth Order of the cosmic hierarchy and revered as the guardians of the mortal world, dispatches emissaries to counter the Lystrians' influence, but the king thwarts their efforts. Consequently, the core of humanity begins to mirror that of the Lystrians-their inner light dims, and their spiritual essence hardens. As eternal winter sets in, Everia makes a final effort to restore the balance and sends WILONA to the mortal realm to challenge both the king and the Lystrians. Human-reborn Wilona, adopted by King Linus, becomes a cherished figure known for her exceptional wisdom and compassion. Guided by MAGISTER FILBERT, a sage bridging celestial and mortal realms, she is poised to become the heir.
Wilona embraces life as a mortal princess, unaware of her true purpose and origin. Her extraordinary abilities are evident in a range of talents, especially her unparalleled combat skills, which are on full display during a tournament where she bests every knight at thirteen. With her feats stirring widespread rumors, Wilona realizes that she is far from ordinary and consciously conceals her abilities, opting to lead a humble existence. She immerses herself in learning, dedicating countless hours to the library, the lab, and the crestlings' village, which she discovers by chance. The crestlings perceive her divine essence and become her allies, teaching her the art of sound.
Being the king's adopted daughter, Wilona encounters opposition to her claim as the future ruler, especially from Flavius, Linus's younger brother who rules neighboring Alambia. Flavius advocates for his son, Marius, a true-born Ammanon, to be recognized as Primatia's heir. Linus disagrees. This dispute fuels a prolonged feud between the brothers. However, the emergence of LUCIUS, a new conqueror from the west, rapidly overtaking neighboring kingdoms, forces Linus and Flavius to form an alliance. They plan to marry Wilona to Marius, uniting the kingdoms under their joint rule. Wilona opposes the marriage.
The plot thickens when Wilona meets and falls in love with DARRION, the Alambian commander. A significant revelation comes when Darrion recognizes Wilona's pendant, linking their destinies.
Lucius advances towards Primatia. Like Wilona, he hails from Everia and possesses remarkable intelligence and a talent for battle strategy. Having swiftly conquered numerous Western kingdoms in just a year, he is a force to be reckoned with.
