This episode introduces two new apprentices, Leo, focused on aesthetic sealing, and Toby, focused on confectionary structure. They are stationed at the massive Sugar Silo, which is exhibiting material failure symptoms mirroring those seen in the felt archives—the sugar is softening, losing its structural integrity while retaining its color, indicating a form of targeted material essence drain. Toby notes localized cold and a deep tremor, connecting the Silo's failure to the subterranean activity confirmed by Tamsin and Bram. Leo recalls lore regarding Resonance Glaze, a material meant to stabilize aesthetic structures against ground interference. They breach the restricted Oversized Display Archive to retrieve this glaze. As they secure the glaze, they hear the loud, rhythmic scraping noise, confirming the subterranean threat is directly beneath them, escalating the immediate structural danger to the entire Silo.
