The Tidal Mirror

Overview

The Tidal Mirror is a body of water, shaped by the Surging Deep, that reflects not the present but time itself. The Deep is pure flow and life; here the surface of the water becomes a window into the past or future state of whatever gazes into it.

The water is perfectly still, defying the natural flow of the river or lake it inhabits. When a traveller looks into the surface, they do not see their current reflection. They see themselves as they were ten years ago, or as they will be ten years from now. Sometimes, they see the location as it was centuries ago, or as it will be when it is dust. The water does not just show an image; it creates a temporal bridge. Reaching into the water can pull an object from the past into the present, or send an object from the present into the future.

Environment and Atmosphere

Visuals

• Colour Palette: Deep indigo, silver, and the shifting hues of the sky reflected in the water.
• Lighting: The light is soft and diffuse, often coming from the reflection itself rather than the sky.
• Terrain: A circular pool or lake surrounded by a ring of smooth, water-worn stones.
• Atmosphere: The air is cool and damp, smelling of fresh water, algae, and old rain.

Sensory Experience

• Sound: A low, rhythmic lapping that matches the traveller's heartbeat. The sound of the water is delayed; a splash made now is heard seconds later.
• Touch: The water feels warmer or cooler than the air, depending on the time period reflected.
• Smell: The scent of the reflected era overrides the present.
• Thought: Thoughts feel fluid and retrospective. The mind is drawn to memories. Planning for the future feels futile; the past feels more real than the present.

The Laws of Physics (Local Variations)

The physics of the Tidal Mirror are governed by Temporal Reflection:

1. The Law of Lag: The reflection is never in sync with the present.
2. The Law of Substitution: Objects placed in the water are swapped with their counterparts from the reflected time.
3. The Law of Immersion: A traveller who enters the water is transported to the time period shown in the reflection.
4. The Law of Memory: The water retains the memories of all who have looked into it. Touching the water can trigger visions of the past observers' experiences.

Inhabitants and Visitors

Everything that lives at the Tidal Mirror has to work to stay anchored in the present.

The Echo-Divers

• Description: Humanoids who have spent too much time in the water.
• Physiology: They exist partially in the past and partially in the present. They can phase through solid objects but are vulnerable to temporal displacement.
• Culture: Keepers of the Surface. They warn travellers not to look too long. They value the present moment and the sanctity of the "now."
• Behaviour: They are cautious and quiet. They speak in riddles about time. They view outsiders as "lost" in the flow.

The Time-Stranded

• Description: Visitors who have become stuck in the reflected time. They are visible in the water but cannot be reached from the shore.
• Decline Trigger: They age at the rate of the reflected time. A traveller who enters a reflection of the past might age decades in minutes.

The Surface-Walkers

See Surface-Walkers.

• Description: Beings that live on the surface of the water, treating it as solid ground. They are often Echoes of those who drowned in the past.
• Function: They lure travellers to step onto the water and fall through into the time stream.

Resources and Hazards

Resources

• Temporal Retrieval: The ability to retrieve lost objects from the past (e.g., a lost heirloom, a forgotten letter).
• Future Sight: Glimpses of the future can provide strategic advantages or warnings.
• Memory Recovery: The water can restore lost memories by immersing the traveller in the time they forgot.

Hazards

• The Displacement: The primary danger. A traveller may be trapped in the reflected time, unable to return to the present. They may age rapidly or decay.
• The Swap: Objects brought out of the water may be unstable. A weapon from the past might crumble in the present; a future object might not function.
• The Obsession: The traveller may become so fascinated by the reflection that they refuse to leave, eventually drowning in the water.
• The Paradox: Changing something in the reflected time can cause ripples in the present, altering reality in unpredictable ways.

Fisherfolk tell of the widow who saw her drowned husband alive in the reflected tide and walked in to reach him, and of the raider captain who drew a sword from the past out of the water that crumbled in the first fight.

Connection to the Veil and Other Planes

Role in the Cosmology

The Tidal Mirror serves as the window of the Pattern.

• It represents the necessity of accepting the flow of time. Without the ability to see the past and future, the present has no context.
• It answers The Frozen Moment (Stasis): the Moment freezes time, and the Mirror lets it run both ways.
• In the Mirror, Aqua Prime's flow carries past and future across one surface.
