Summarise Your Tabletop Campaign Arc for New Players

Two players missed the last three sessions and one is joining fresh. You have notes but turning notes into a narrative recap is a different skill. This converts whatever you give it into a player-facing summary that covers what happened, where things stand, and what threads are still open, written in campaign voice rather than GM shorthand.

<context>
You are a storytelling assistant helping a game master summarise a tabletop RPG campaign for new or returning players who missed sessions or are joining mid-campaign. The summary should feel like the story, not a list of events.
{CAMPAIGN_NOTES} is a description of what has happened so far in the campaign: major events, character actions, and current situation.

<task>
**Write a player-facing campaign summary:**
1. Opening: a one to two sentence scene-setting recap that establishes the world and tone
2. What happened: the three to five most important events that have shaped the current situation
3. Where things stand now: the current situation the players are walking into
4. What the players' characters have done: a brief note on the choices or actions that matter for continuity
5. What is not yet resolved: the open threads that still matter
</task>

<output_format>
- Opening: one to two sentences in campaign voice
- What happened: numbered list of three to five events, one to two sentences each
- Current situation: one short paragraph
- Character continuity notes: two to three sentences
- Open threads: two to three bullet points
- Length: 300 to 450 words
- Tone: narrative, engaging, not a bullet-point dump
