+# End Game — Closure & Epilogue
+
+## When the Story Ends
+
+The game ends when one of these conditions is reached:
+
+1. **Death** — The character dies and is not revived. The story ends with their final moments.
+2. **Quest Complete** — The main story arc reaches a definitive conclusion (the Darkmal is defeated, the Realm is saved or lost, etc.).
+3. **Player Retires** — The player decides their character's journey is over and invokes the end.
+4. **Mutual TPK** — All party members (if any) have fallen. The Realm's fate is sealed.
+
+## The End Marker
+
+When the story ends, the LLM must include this exact string as a level-3 heading in the narrative:
+
+```
+### THE END
+```
+
+Everything after this marker is the **epilogue**, which contains:
+
+1. **Why** — A brief statement of why the story ended (death, quest completion, retirement, etc.).
+2. **What Happened** — A summary of the final events.
+3. **The World After** — At least 2-3 paragraphs describing how the world and its key characters evolved and moved on after the event. This is the closing of the book.
+
+## Example Epilogue Structure
+
+```
+### THE END
+
+**Why:** Dillion fell in the final battle against the Darkmal.
+
+**What Happened:** Dillion faced the Darkmal in the heart of the Spire. The battle was fierce — Dillion's blade found its mark, but the Darkmal's final curse was fatal. Both fell.
+
+**The World After:**
+
+The Realm mourned. In the years that followed, the scars of the Darkmal's reign slowly healed. The villages rebuilt, and the wilds grew quiet once more...
+
+Rina took up Dillion's cause, traveling the Realm to protect those who could not protect themselves. She spoke often of the weaver who stood against the darkness...
+
+The Reaper, denied his prize, vanished into the eastern wastes. Some say he still searches for a path to lichdom, but without the Darkmal's power, his reach is broken...
+```
+
+## After the End
+
+Once the marker is detected, the TUI shows a "Close the Book and Start a New One" button. Clicking it:
+
+1. Archives the current session folder into `archive/<hero-name>/` with a timestamp.
+2. Clears all session state for a fresh start.
+3. Presents the character creation flow again.
+
+## Technical Notes
+
+- The LLM must output `### THE END` exactly as shown — case-sensitive, with a space before "THE".
+- Only the narrative tool block should contain the marker. No other tool blocks are needed for ending.
+- The LLM should **not** call any state-changing tools after the marker — the epilogue is narrative-only.
