A sinister, ethereal artifact that emits a faint, ominous glow, resembling swirling shadows condensed into a tangible form. Its core is a dark, pulsating orb encased in intricate, skeletal-like metalwork that appears both ancient and malevolent. The surface is smooth yet gives the illusion of depth, as if staring into an abyss, with subtle runes etched along the metal that glow a eerie purple when activated.
