7000 Castles — Book IV: The Building. 7000 Castles

The Seven Thousand Castles: The Awakening ApparatusFor centuries, humanity believed the Seven Thousand Castles were a monument to human ambition-grand fortresses built across the surface of the continent to protect the kingdoms from war, invasion, and each other. They were wrong. When High Architect Edravin accidentally breaches a lightless, prehistoric vault deep beneath the foundations of Valdoria, he triggers a global chain reaction.
Across every nation, the earth fractures. Unfinished structures begin to unfold like mechanical origami. Ancient elevator shafts grind upward from the abyss, and forgotten tunnels reopen beneath forests and boiling seas. The castles are not construction projects. They are an awakening apparatus.
