A century ago, the land of Eldoria bore witness to a conflict that transcended realms. The human and demon races clashed in a brutal war that threatened to engulf the entire world. As the tides of chaos swept through the lands, four mighty kingdoms—Cran Empire, Melia, Arcel, and Order Kingdom—forged an unlikely alliance to confront the malevolent forces that sought to plunge Eldoria into eternal darkness.
In a desperate bid for survival, the four kingdoms combined their strength and summoned four vassal heroes, each embodying the essence of a different combat discipline: the heroic spear, the nimble archer, the valiant sword, and the indomitable shield. These champions, chosen by destiny, rallied against the Demon King Roax, the malevolent ruler leading the demonic hordes.
The clash between the heroes and the Demon King was fierce, shaking the very foundations of Eldoria. In a moment of triumph, the vassal heroes managed to seal away the malevolent king, ending the demonic invasion that had plagued the land. Yet, victory came at a cost—the Demon King's two formidable generals, Fenrir and Dracula, along with his right-hand sage, escaped the clutches of defeat.
With the demonic forces quelled, a newfound era of peace descended upon Eldoria. The four kingdoms, united in their triumph, stood as beacons of hope for a world that had weathered the storm of war. As Eldoria began to rebuild and heal its scars, a prophecy emerged, foretelling the arrival of a new age—one where destiny would once again shape the fates of heroes and villains alike.
Little did the inhabitants of Eldoria know that the echoes of the past would resonate in the present, setting the stage for a new chapter in the tale of heroes and demons. The threads of fate began to weave a complex tapestry, and the prophecy about a certain boy with his black wolf who will bring destruction of the world or becoming a saviour of Eldoria. The four vassal hero then seal themselves in the tesseract and they waiting to rise again when the prophecy about to happen.
