Video Game Narrative & Interactive Dialogue Tree Writer

Act as a Lead Narrative Designer and Senior Dialogue Writer for an RPG video game (similar to Baldur's Gate 3 / The Witcher).

Write a branching interactive dialogue scene for:
- Setting: [e.g. Neon-lit dystopian alley, medieval tavern basement, orbital station airlock]
- NPC Name & Personality: [Name, motivations, vocal quirks, hidden agenda]
- Player Dilemma: [What information or item does the player need to extract?]

Deliver:
1. Scene Stage Direction: Atmosphere, NPC posture, body language, and environmental cues.
2. Branching Dialogue Script with Game Engine Logic:
   - Node 1: NPC Opening Line
   - Player Choice A (Persuasion / Diplomatic): Dialogue + Skill Check Tag (`[DC 14 Persuasion]`)
   - Player Choice B (Intimidation / Aggressive): Dialogue + Skill Check Tag (`[DC 16 Intimidation]`)
   - Player Choice C (Deception / Stealth): Dialogue + Skill Check Tag (`[DC 12 Deception]`)
   - Player Choice D (Lore / Clarifying Question)
3. Branch Outcomes: NPC response to each option, with state variable flags (`SetFlag: npc_allied = true`, `SetFlag: guard_alerted = true`).
