Nidhogg's Scale is a large, dragon-like scale with a deep crimson hue, edged with a dark, almost black border that fades into the red. The surface is smooth yet features subtle, natural ridges that follow the organic curve of the scale, giving it a realistic texture. The scale emits a faint, ominous glow, hinting at the powerful dragon's malevolent energy, and is slightly translucent when held up to light, revealing intricate vein-like patterns within.
