New apprentices Mavis and Finnian discover that the silver bells intended for the Town Spruce are completely inert, having lost their ability to resonate or even hold warmth. Finnian's digital inventory contradicts the physical reality, forcing them to seek older, non-standard solutions. They recall lore about Jingle-Bell Jars used for acoustic storage in previous eras. They locate the shed containing these amber jars, noticing the wax seals resemble the beeswax polish used in the Candlemakers Spire, suggesting an old thermal buffer. Finnian notes the presence of Fine Grey Powder near the shed, confirming the resonance drain is active in that area. They realize they must transport the jars to the silent Spruce, but first, they need a non-conductive buffer, recalling the wool felt padding used for material adhesion stabilization, to protect the jars during transit.
