The Field Journal is the centre of the card system. It unlocks card tracking, clue logging, and case-file storage. Clue cards, evidence cards, and route notes can be physically kept behind it, turning the journal into the player’s real-world case file.

The Brass Bell is a single-use item card. Ring it to test whether a sound, echo, path, door, or presence is real. Once used, discard it from the Inventory Ring.

Black Thread is a route-marking item. Use it to mark a corridor, trail, room, or return point before the location changes. It can prevent one loop, false route, wrong hallway, or map-shift effect.

Witness Note is a clue and evidence card. Place it inside the Field Journal or Case File. It can unlock extra choices when the game asks for proof, testimony, memory, or contradiction.

Forced Silence is a ritual event card. Play it to trigger a safe Loading Ritual where players stay silent for a short time and report the first sound they notice. That sound enters the next scene.

Last Light is a held event card. Keep it in reserve until a danger event, failed search, or Presence spike. When played, it cancels one Fear increase, then goes to the discard pile.

Marked is a burden card. Keep it active beside the Inventory Ring until cleared. While Marked is active, the next failed search, wrong route, or risky action may increase Presence.

Rust Key is a key item card. Use it when a sealed, stuck, hidden, or symbolic door appears. Unless the game says the key remains, discard it after use.

False Memory is a burden and clue-corruption card. Keep it active beside the Journal. While active, one remembered clue may be unreliable until verified through another card, map, journal entry, or photo reveal.

Safe Return is a safety card. Hold it in reserve and play it to pause the current scene, return to a safe point, recap the case, or step out of the game. It is reusable unless a specific mode marks it as single-use.
