+# Character State: ch-18
+
+## Elias Thorne
+Location: Archive Sub-Level 4, Signal Transmission Chamber
+Physical: Severe exhaustion; bleeding from ears/nose due to acoustic pressure; partial hearing loss.
+Emotional: Transcendent but grieving; a sense of hollow victory.
+Active obligations: owes Sarah Miller a full explanation of the signal (Ch-17) -- PAID.
+Open loops: [Elias & Signal] fate of his consciousness after the server overload (Ch-18) -- UNRESOLVED.
+Known secrets: CARRIED (Ch-17--unresolved): Signal mimics voices of the dead -- [Sarah Miller].
+Arc: 100% -- Transitioned from investigator to the physical conduit that silenced the broadcast.
+Permanent: YES
+
+## Sarah Miller
+Location: Archive Sub-Level 4, Security Monitoring Hub / Maintenance Access
+Physical: Migraine subsided into a dull ache; bruising on forearms from server bracing.
+Emotional: Devastated; struggling to reconcile her rationalism with the supernatural sacrifice witnessed.
+Active obligations: owes Elias a backup extraction route (Ch-17) -- FAILED (Terminal was destroyed).
+Open loops: [Sarah & Archive] surviving the facility collapse/containment (Ch-18) -- UNRESOLVED.
+Known secrets: CARRIED (Ch-17--unresolved): Archive security sabotaged from inside -- [Elias Thorne].
+Arc: 95% -- Fully surrendered to the supernatural reality, prioritizing the mission over her own safety and logic.
+Permanent: YES
+
+## The Curator
+Location: Administrative Level (Inferred)
+Physical: Unknown
+Emotional: Unknown
+Active obligations: None.
+Open loops: [The Curator & Sabotage] his specific role in the internal security override (Ch-17) -- UNRESOLVED.
+Known secrets: Unknown.
+Arc: 0% -- Remained an off-screen influence/antagonist.
+Permanent: NO
+
+# World State: ch-18
+
+## NPC Memory
+- High-Frequency Entities (The Whispers): HOSTILE -- Attempted to possess the transmission hardware -- Temporarily silenced by Elias's override.
+
+## Faction Attitudes
+- The Archive (Oakhaven): TERMINATED -- The facility has entered a hard-lockdown self-destruction/containment state following the signal surge.
+
+## Active World Events
+- The Terminal Broadcast: SILENCED -- The countdown to surface transmission reached zero exactly as Elias initiated the feedback loop, destroying the primary transmitter.
+- Facility Collapse: ACTIVE -- Structural integrity of Sub-Level 4 is failing; automated fire suppression and containment locks are triggering.
+
+## Secret Carry-Forward
+- Elias Thorne's secret (Signal mimics the dead) remains unresolved as Elias did not survive or remain in a state to communicate this effectively to Sarah before the final surge.
+- Sarah Miller's secret (Internal sabotage) remains active as the specific identity and motives of the saboteur (The Curator or others) were not revealed during the confrontation.
