Excalibur

Lore & Background

During the Great War three thousand years ago, Arthur wielded Excalibur alongside his comrades against the Demon King's forces. The sword became a beacon of resistance, its power capable of severing connections between demons and their dark energy sources. Even in later timelines when Arthur returned to aid the Sins, the blade remained a testament to his unwavering commitment to protecting humanity from supernatural threats.

In Their Own Story

The air grew heavy with the scent of ozone as King Arthur stepped forward, his armor gleaming under the moonlight. With a steady hand, he drew Excalibur from its scabbard, and instantly, the darkness around him recoiled. The blade hummed with a soft, blue luminescence that cut through the shadows like dawn breaking over a winter sea. He did not need to shout; the sword itself spoke of judgment against the monsters before him.

Reader's Guide

Excalibur functions as a conduit for immense holy energy, specifically designed to counter demonic entities. Unlike standard steel, its blade vibrates with light that inflicts spiritual damage alongside physical cuts. This radiant emission burns through dark magic and corrupts demon flesh upon contact. The sword's power scales with the wielder's purity of heart and resolve. King Arthur Pendragon demonstrated this by channeling his will to amplify the blade's reach, creating waves of light that repelled entire armies. However, maintaining this output drains physical stamina rapidly. Visually, the weapon glows with a soft blue or white luminescence during activation. While primarily associated with Arthur, the sword requires a user capable of resisting its holy pressure to avoid injury. Its legacy remains unmatched as a symbol of resistance against the Demon Clan's tyranny throughout Britannian history.
