Apprentices Cassian and Riona, tasked with final quality checks in the Wrapping Annex, discover that the Whisperwind Music Box destined for Frostfall has been sabotaged. The insulation padding has been replaced with a material that actively absorbs resonance and dampens the sound mechanism. Riona confirms the material is actively pulling energy using an older resonance reader. Cassian realizes this constitutes a failure of the delivery chain integrity, forcing them to violate protocol. They decide to use a restricted Logistics Guild key to access Sub-Level Three, Section Gamma, where specialized chime-metal lined dampening strips are stored, hoping to find untainted material. As they move toward the restricted sub-level, Riona notes that the frantic skipping vibration felt earlier near the Sleigh Bay is now returning beneath their feet, suggesting the subterranean activity is escalating and closing in on the Wrapping Annex.
