The Gravitational Canticle vibrates at frequencies matching competitive interactions, creating a resonant hum that sensitive observers can perceive during high-stakes rounds. It appears to shift in weight based on the ranking position it represents - heavier when carrying the weight of a high tag, lighter when bearing a lower number. It emits a low harmonic hum when bag tag transfers occur, as if the universe itself is singing the change in competitive hierarchy. The artifact changes color based on the gravitational significance of recent transfers, glowing brighter after dramatic upsets that send ripples through the competitive order.

The Gravitational Canticle serves as a living record of every bag tag transfer, its vibrations accumulating into an ever-growing harmonic that the Grays use to assess humanity's geometric worthiness.
