The Ouma Empire Sword & Katana Lore

The Ouma Katana is no ordinary blade, it is the soul of an empire forged in fire, discipline, and destiny. Wielded by Raiketsu of the Black Flame, the last sworn protector of the Ouma bloodline, this katana served as both executioner and shield. Known for its deep obsidian blade with crimson streaking through the hamon like veins of magma, the sword symbolizes the inner conflict of a warrior bound by honor yet torn by rebellion. Passed down through generations of imperial swordmasters, the Ouma Katana was said to be folded from steel touched by celestial flame, a weapon granted only to those who mastered the dual path of war and restraint.
