Fierce Fire: Medieval Western Fantasy, the Road of Knights

Tristan was once the most dazzling and youngest titled knight in the empire, until he closed the eyes of his best friend with his own hands in that battle whose name was erased by history. From then on, the corridor of life and death stretched under his feet, and behind each stone door stood his past self - the boy who insisted on chivalry, the death knight whose sword was stained with blood, and the traitor in the ruins of the outpost. The millstone of blood and fire crushed his armor, but forged something harder, the flames that burned all night, and the red and unparalleled weapon. He is upright, fiery, and unafraid of sacrifice, but where is his path, the path of these knights, and the ultimate destination they want to reach?
