Apprentices Silas and Tamsin are introduced at the Observatory Annex Storage Lock to inspect the Stardust Infusion units. They immediately notice a localized energy drain affecting the crystalline light gels, causing the silver fittings to dull. Silas recalls the need for non-conductive buffering mentioned in old maintenance logs, connecting their current problem to the wider resonance crisis affecting other areas of Silver Creek. They successfully use Tannery Linen, a material previously used by other teams, to insulate the silver fittings of Unit Seven, stopping the thermal drain and causing the internal temperature to rise slightly. This action dislodges a small, warm, waxy piece of correspondence sealed with a silver star, bearing the message Seek the Warm Reply, providing a direct, warm clue amidst the cold structural failures.
