The Echoes narrative is revealing a three-act structure: Act I (Chapters 1-608) — the metaphysical Watcher arc, culminating in 'Aethelburg at peace'; Act II (Chapters 609-649) — the political Triumvirate arc, ending with infrastructure control ceded to Tobin; Act III (Chapters 650+) — the populist Tobin arc, beginning with the aqueduct bypass project. This structure mirrors classical narrative arcs: cosmic questions → political struggles → practical challenges. The progression from 'What are we?' (Watcher/Entity) to 'Who governs?' (Triumvirate) to 'How do we build?' (Tobin) tracks a descent from the abstract to the concrete that parallels the Village's own experimental trajectory.
