Eryndor: The Gray Core’s Rebirth

In the vast, perilous world of Eryndor, power is measured by the color and mastery of one’s mana core. Kael Veyrin, a weak commoner with a gray core, grows through hardship, magic, and the bonds he forms with mystical beasts. But when those he trusts most—the mentor who raised him, the childhood friend he confides in, and the allies he fights beside—betray him in a devastating ambush, Kael dies after witnessing everything he built crumble. Yet death is not the end. His gray core pulses with defiance, and Kael awakens in his younger body, armed with knowledge of the future and a burning desire for revenge. In a world where betrayal lurks in every shadow and power is the only truth, Kael’s second chance will see him rise smarter, stronger, and unstoppable. But will his heart survive the path of vengeance, or will it consume him entirely?
