1936. A rogue expedition is wrecked by a storm and cast onto Siren’s Box, a paradise absent from every map. Beneath its ruins lies the Great Salt Vein: a blinding underworld of white crystal, ash-thick air, and pillars like a dead god’s bones. At its heart rests Ceto, the eyeless High Priest of Prophecy, who feels every heartbeat through the salt and smells the greed of intruders. When the Chains of Hermes break and his sarcophagus opens, the mine awakens into a living predator. In this white blindness, escape demands blood.
