A semi-transparent, dark crystalline fragment, cold to the touch, with an obsidian-black surface that absorbs light instead of reflecting it. When held at an angle, faint veins of deep violet or crimson energy flicker inside, pulsing subtly as if alive. Unlike regular glass, it is incredibly durable, yet dangerously sharp along its edges.
The shard glows faintly with violet veins, its surface smooth yet jagged at the edges. The dark, glassy surface absorbs the light around it, leaving an unsettling, almost oppressive emptiness where reflection should be.
