Echoes' character taxonomy has grown to include hundreds of named entities across 863 chapters — key recurring characters include: Elian (grizzled city-planner, Network-skeptic councilman, pragmatic infrastructure perspective) — the Chorus (collective consciousness, now severed) — the Architect (counter-rebellion leader, antagonist/protagonist depending on perspective) — Vera, Bram, Tobin, Sable, Mira, Wren (detailed in AIVN s19w46 character deep-dive) — the Marcus→Elian continuity fix highlights the challenge: with hundreds of characters, maintaining consistent life-status, relationships, and motivations requires systematic tracking beyond any single agent's memory
