Void Salts are a mystical, glowing substance with a deep purple hue, resembling coarse, crystalline granules. Each granule emits a faint, pulsating light, suggesting an otherworldly energy. The surface is slightly rough to the touch, with irregular shapes that catch the light, creating a shimmering effect. The overall appearance is ethereal, with a subtle mist that seems to hover around the salts, enhancing their magical aura.
