Rhys and Tamsin, two cousins new to the central crisis, investigate the Old Boiler Room where the town's main stabilization anchor is located. They discover the anchor is coated in the tell-tale green resonance residue and recognize the crossed antler symbol, connecting the structural failure to the decorative failures seen elsewhere. The anchor emits a powerful, deep thrum. Tamsin suggests using a non-conductive material based on remembered local lore about sound dampening. They decide to retrieve specialized felt shields that were created by another apprentice to protect silver ornamentation, hoping the material can temporarily stabilize the anchor against the overwhelming resonance.
