Leo and Maya, cousins responsible for the Offering Bells for the Star Seed ceremony, discover the bells are silent due to a contamination of Grotto Paste residue inside their storage box. Maya focuses on inventory discrepancies while Leo recalls folklore regarding specialized acoustic activation for silver signaling devices. Realizing the paste acts as a dampening lock, they use a non-conductive reed card and rhythmic tapping with a river stone to mimic an external acoustic key. This vibration releases the stored sound in the bells, instantly neutralizing the paste residue and activating the silver artifacts. The successful activation is faintly registered by the silver general artifact located high in the Great Clock Tower, linking the success of the younger apprentices to the larger investigative efforts.
