No iron or steel. I searched inside for a fractal sword that would bend incoming light to the intricacies of its inner form, and I found it in my dream. It was buried far beneath the central citadel, silent near the burning core of its origin. Somehow I pulled it out of that world and into this, and yet it became more subtle still. Elegant and deadly, the elusive edge of the blade distorts the texture of reality as it slices through the air, each movement trailed by prismatic spray. My comfort and protection, ever at my side; with such a sword, I have no need of any shield.
