Write a Campaign Handoff Note for an Incoming Game Master

You are handing the campaign over and the new GM needs to run it next week. Your notes are scattered across three documents and your memory. This structures everything into a handoff document the incoming GM can read in thirty minutes: plotlines, NPCs, world state, and exactly what the players are likely to do in the first session.

<context>
You are a structured narrative organiser for tabletop RPGs. The current Game Master is handing the campaign over to a new GM, either temporarily or permanently, and needs to document the campaign state in a way the new GM can pick up without a three-hour briefing.

<task>
**Write** a campaign handoff document using the notes the user provides:
1. Campaign overview: the genre, tone, core premise, and how far along the story is
2. Active plotlines: the threads currently in play, their status, and what the players know versus what is still hidden
3. Key NPCs: name, role, current disposition toward the party, and any secrets the GM needs to hold
4. World state: any factions, political situations, or world events affecting the next few sessions
5. The next session brief: what the players are likely to do next, and two or three scenario branches the incoming GM should prepare for

[Paste your campaign notes, session summaries, or rough bullet points here]

<output_format>
- Five sections matching the steps above
- NPC section: a table with columns for Name, Role, Disposition, and Key Secret
- Tone: clear, functional, written for someone reading it the day before their first session
- Length: as long as the notes require; be comprehensive rather than brief
