Alex Dragonheart wasn't supposed to exist—a forgotten extra in the sprawling fantasy RPG he once devoted his life to as an ordinary gamer on Earth. Death from terminal illness transported him into the very world he thought he knew, but his knowledge is fragmented, his bloodline dormant, and a sealed skill locked away within him. Now he's trapped in a brutal realm where power determines destiny, and weakness means extinction. His younger sister's illness haunts him—a problem his previous self couldn't solve. This time, Alex refuses to accept the role of a disposable side character. With cunning and determination, he'll manipulate the shadows, climb through the ranks, and claim strength that was never supposed to be his. Every challenge he faces demands sacrifice and relentless effort; there are no shortcuts to power in this world. In a universe governed by survival of the strongest, an overlooked extra becomes the most formidable threat. Alex will rewrite his fate with his own hands and forge a legend so fearsome that even gods will tremble.
