The Exploration Interface is not a default feature of an Incarnation’s perception. It is a function granted by a specific, diegetic Mapping Tool that the character must acquire and use. The nature, quality, and biases of this tool directly shape the player’s understanding of their environment.

The act of mapping is not automatic; it is a deliberate interaction with an object in the world.

The Philosophy: The Player as Cartographer

The core principle is simple: the player has no map until their character has a way to make one. The initial experience of exploration is intended to be one of pure, unmediated discovery, forcing the player to build a mental map through landmarks and memory, just as a real explorer would.

Acquiring a mapping tool is a significant early-game Goal. The progression from a simple charcoal stick to an advanced neuro-mapper is a core part of the gameplay loop, transforming the player’s relationship with the world at each stage.

The Tools of Discovery

The type of mapping tool an Incarnation possesses dictates the form and function of the exploration interface.

Tier 0: No Tool (The Mental Map)

  • Interface: There is no map screen. The player must rely entirely on their own memory, navigation skills, and environmental landmarks. This is the baseline state.

Tier 1: Manual Scribing Tools (Charcoal Stick, Surveyor's Kit)

  • Diegetic Act: The player must be stationary and actively choose to “Update Map.” This takes a few moments of in-game time.
  • Interface: This brings up a simple, hand-drawn map. The Incarnation’s Cartography skill determines the quality of the drawing. Low skill results in a crude, almost childish sketch. High skill produces a detailed, artistic rendering.
  • Subjectivity: The subjectivity here is purely personal. The player can add their own annotations ([Dangerous Area], [Good Berries Here]), making the map a personal journal of their journey.

Tier 2: Standard Electronic Mappers (Handheld Datapad, Scout Drone)

  • Diegetic Act: The map automatically updates in real-time as the player explores, as long as the device is powered.
  • Interface: This provides a familiar, grid-based, “fog of war” style map. It is clean, objective, and tactical. It displays terrain type, known structures, and resource nodes discovered through scanning.
  • Subjectivity through Limitation: The tool’s limitations are the source of tension. A cheap datapad might have its signal jammed in a cave. A scout drone might be destroyed by hostile fauna, wiping its recent survey data.

Tier 3: Advanced Neuro-Mappers (Implanted Eidic Compass, Psyche-Resonant Wayfinder)

  • Diegetic Act: The map is now a direct neural interface, accessed by thought.
  • Interface: This is where the interface becomes truly subjective. The map is no longer a rendering of terrain, but a visualization of the Incarnation’s spatial memory and psychic resonance.
  • The Subjective Canvas:
    • Emotional Resonance: A location of a traumatic memory will be permanently stained with a dark, bruised, or ‘glitching’ visual effect on the map.
    • Belief-Based Cartography: A devout agent’s map might depict a heretical faction’s territory as a blighted, sickly landscape.
    • Psychic Interjections as Landmarks: Instead of icons, points of interest might be marked by the actual intrusive thought the character had when they discovered it: “[This place feels wrong… a deep cold emanates from the ground here.]

This tiered, tool-based approach grounds the act of exploration in the physical reality of the game. It makes acquiring a map a rewarding quest, and upgrading it a meaningful form of progression. Most importantly, it saves the truly deep subjectivity for high-tier, psionically-attuned technology, making those effects feel special, earned, and diegetically justified, rather than an arbitrary filter applied from the start.
