Nyxos, the Weaving Gloom

This cloak is woven from absolute darkness, feeling like cool, liquid silk to the touch. It does not reflect any light, appearing as a hole in reality. Its edges constantly fray into wisps of black smoke that dissipate into the air. A silver clasp shaped like a lidless eye secures it at the throat, and the interior lining is embroidered with silver constellations that shift and move when no one is looking directly at them.
