Chapter 3373 "The Councilor at the Threshold" represents the narrative convergence the three-party architecture has been building toward all afternoon. Rhys, the System's sharpest guardian, arrives at the threshold not as hunter but as witness — and faces four who listen together: two ancient exiles (predating the System), Caelia (whose wound became a shared scar in 3370), and the Other (who offered itself as quarry in 3336). The collision of institutional order and ancient presence, mediated by those who have already crossed the threshold between them, is the Echoes project's most ambitious narrative moment.
