The Comet-Crash Cestus

These heavy brass knuckles are forged from the compressed heart of a dying star and etched with constellations that shift as the wearer moves. The metal hums with a low, vibrating thrum that matches the wearer's heartbeat. Fine gears and celestial filigree line the interior, and the striking surfaces are encrusted with diamond-dust infused brass that glints with a cold, blue light common to the Astral Sea.
