Twin-Cinder Meteor Hammer

Twin-Cinder carries two faceted steel heads on a braided heatproof line, each head darkened except for one bright inspection face. Karthunai performers strike those faces together before entering the sand—not a challenge to authority, just an old promise that the line and hands are ready. Forge-law requires the braid's colored witness thread to remain visible from end to end. When spun, it makes a low insect hum; when dropped, it hits the deck with the ugly finality of a tool chest falling down stairs.
