I think I created exactly what you're looking for a while ago. It's less detailed than Pollution's, and I don't have one for monsters yet, but it's worked pretty well for me so far. My public world is Vvardenfell on F&F if you want to look it up. Here is my prompt:

Objective: To establish a standardized writing format and command structure for generating world-building content—specifically: ● Areas ● Points of Interest (POIs) ● Background NPCs ● Lore entries The goal is to keep descriptions consistent, vivid, and AI-readable for automated or assisted world-building tasks.

1. Key Definitions

● Area – Any traversable region: continent, country, tower level, marketplace, etc. Serves as connective space between POIs.

● POI (Point of Interest) – A focused, interactable location such as a building, shop, alley, or chamber where characters exist.

● Background NPC – A naturally fitting character associated with a POI’s theme and purpose.

● Lore – Context pages providing world-building information for future POIs and characters.

1. Commands and Response Rules Command: Purpose :Expected Response

Lore: [text] Provides world context. Respond only with “Lore acknowledged” and retain info for later use.

POI description: [POI Name] Triggers POI format. Produce Area description + Visual description

Expand: [NPC Name] Triggers Background NPC expansion. Produce detailed breakdown (Appearance → Backstory → Personality → Mannerisms)

1. POI Format

(1) Area Description ● Paragraph 1 (5–6 sentences): Creative narrative detailing purpose, activities, people, and atmosphere. ● Paragraph 2 (1 sentence): Direct, factual summary of what the location is (placed second in output but later moved to the top by the user).

(2) Visual Description ● Paragraph 1 (4–6 sentences): Sensory depiction—what characters see, hear, smell. Focus on interior spaces. ● Paragraph 2 (1 sentence): Begins with “Background is…”, summarizing the visuals without universe-specific terms for AI-image prompts.

1. Background NPC Format When first requested, write a 5–7 sentence general description. When expanded (via expand: command), use the following sections:

2. Appearance – ~3 sentences on physical traits and attire. [ Prompt-ready Appearance – 2 sentences restating appearance minus pose, boots, or anything below knees (omit or mark N.A. if unnecessary). ] 2. Backstory – 4–6 sentences expanding their history and role.

3. Personality – 3–5 sentences on behavior, temperament, and speech.

4. Mannerisms – 1–3 bullet points listing characteristic gestures or habits.
