Summarise a Tabletop RPG Campaign for New Players

Someone's joining the table mid-campaign and the party has eight sessions of history behind them. Point this at your notes and it writes a catch-up briefing: who everyone is, what's happened, and what matters right now, pitched so the newcomer isn't lost by the first roll. For DMs welcoming a player partway through.

<task>
**Summarise the campaign clearly:**
1. Write a one-paragraph world and premise overview that orients a newcomer without spoiling future plot
2. Describe the current party members (existing player characters): name, one-sentence role, and one personality trait the new player will encounter in play
3. Summarise the main story arc so far in three bullet points: where things started, the key turning point, and where the party stands now
4. Name the two most important NPCs the new player needs to know, with a one-sentence description of their relevance

**Edge case handling:** If the campaign has significant in-world secrets the new player's character would not know, mark those sections clearly as DM-only context.
