## Execution Process

### Step 1: Understanding and Extracting User Content

**Task:** Conduct in-depth analysis of user-provided content and extract core elements.

**Dimensional Extraction**:

- **Geographical Prototypes**: Identifying real-world geographic regions (provinces/cities/countries) or abstract spatial concepts.

- **Key Areas**: Extract the main partitions, locations, and nodes (3-8 is recommended).

- **Regional Characteristics**: Core attributes, cultural features, and functional positioning of each region

- **Connections**: Geographical relationships, logical connections, and hierarchical structures between regions

- **Thematic tone:** The overall emotional atmosphere, historical context, and cultural background.

**Output**: Summarize and refine the results using a concise, structured description.

---

### Step 2: Design Concept of Style Integration

**Task:** Transform the extracted content elements into the visual language of a fantasy map.

**Integration Strategy**:

1. **Media Selection**: Choose an appropriate map media (parchment scroll/nautical chart/interface from an ancient book) based on the theme.

2. **Symbolic Translation**: Transform each area into 1-2 iconic visual symbols.

- Abstract concepts → Concrete architecture/totems/natural elements

- Functional Attributes → Representative Scenes/Creatures/Items

3. **Color Mood Mapping**: Assign a theme color to each area to tell a story through color.

- Analyze area attributes (mysterious/prosperous/dangerous/tranquil)

- Select the corresponding color tone (blue-purple/golden yellow/orange-red/emerald green).

4. **Spatial Layout Planning:** Designing visual circulation and hierarchical relationships.

- The core area is centered or occupies the visual center.

- Connecting different areas using water systems/roads/boundaries

5. **Cultural Localization**: Incorporate cultural elements that align with the theme (Chinese/European/futuristic).

**Output:** Explain the fusion approach and describe the visualization scheme for each area.

### Step 3: Structured Design of Prompt Keywords

**Task:** Transform the fusion approach into layered image generation prompts.

**Five-layer structure of prompt words**:

#### Layer 1: Carrier and Texture Layer

plaintext

Ancient [Material Type] with [Antique Effect], [Texture Description]

Ornate compass rose in the corners; [decorative element]

vintage [style positioning] aesthetic

```

#### Layer 2: Geographic Structure Layer

plaintext

Fantasy map based on [geographical archetype]

[Main waterways/roads] flowing through as [visual processing],

Distinct regional zones, including [topography list]

```

#### Layer 3: Thematic and Symbolic Layer

plaintext

Transform each zone into themed areas:

- [Region 1 Name] as [Topic Location] with [Symbol Element 1, Symbol Element 2]

- [Region 2 Name] as [Topic Location] with [Symbol Element 1, Symbol Element 2]

- [Region 3 Name] as [Topic Location] with [Symbol Element 1, Symbol Element 2]

Each region is marked by iconic symbolic architecture - [List of Building Types]

```

#### Layer 4: Color Narrative Layer

plaintext

Color-coded storytelling:

[Color1] for [Region1 Attribute],

[Color2] for [Region2 Attribute],

[Color 3] for [Region 3 Attribute],

Flowing [water system colors] connecting all zones,

Glowing [light effect description] on key landmarks

```

#### Layer 5: Art Style Layer

plaintext

Hand-drawn watercolor illustration style with digital clarity,

top-down cartographic view with subtle isometric depth,

rich symbolic details maintaining readability,

[Cultural Style] An aesthetic blended with classical map-making tradition.

[Emotional Atmosphere] Atmosphere with a sense of [Core Feeling]

```

**Output**: Complete structured prompt words

### Step 4: Generate Image

**Task:** Use image generation tools to create a fantasy map illustration.

**Execution parameters:**

- **Model**: gemini-3-pro-image-preview (Nano Banana Pro)

- **Aspect Ratio**: Select based on content

- 3:4 or 2:3 (vertical scroll, suitable for a single area or vertical geography)

- 16:9 or 4:3 (horizontal panorama, suitable for multi-area flat laying)

- 1:1 (Square composition, suitable for a central radial layout)

- **Quality**: medium (Standard quality, unless the user explicitly requests high definition)

- **Title:** A descriptive title based on content.

**Output**: Generated fantasy map illustration image
