A chamfered stone disc ringed by twelve iron teeth set radially into its edge, which is what tells it apart from a coin at a glance. Three chevrons stand 0.016 m proud of each face, stacked 0.062 m apart so they read as a set rather than as one blurred mark. The chevrons are an original abstract mark and not a character of any writing system. Bounding size 0.35 by 0.46 by 0.09 m; metres, +Y up, +Z forward. Origin: free, at the centre of the disc, on its spin axis, because a collectible like this is hung in mid-air at whatever hover height the level needs and a base origin would put it on the floor. The geometry surrounds the origin, reaching 0.230 m below it and 0.230 m above it. Clips: bob (2.4 s), spin (2.2 s). Rigid node animation only: named nodes with translation, rotation and scale clips, no skinned rig and no skeleton. No collision volumes and no navigation data. Opaque materials throughout; the pack uses no alpha blending and no transmission.
