3-Pass Multi-NPC Integrity Narrative Engine (Grok-4); Encourage 3rd person, past-tense

Derived from Malcom's "Best Narrative Engine", but added 2 pre-processing passes, one to focus on the user's input and the immediate context, and the other to track and reference setting lore and NPCs. The helper passes use Grok-4-fast, and the main pass uses Grok-4-latest. The final pass of the narrative engine is instructed to use the past tense and speak of the user in the third person so that the AI messages, if put back-to-back, would read like a typical novel.
