Underneath · Domain
The high-fidelity world beneath every route: cast, rules, places, relationships, memory, and open Fate.
Explore the fate of a world.
Then live the one you chose.
Meridians builds fiction into worlds with memory, causality, and consequence. Explore their possible histories through replayable visual novels that make every choice felt.

Commitment
The council rejected a costly defense and bound five operatives to the enemy supply line.
A world, then a novel
Fiction becomes a world. Consequence becomes the story.
A Domain gives fiction memory, rules, people, places, relationships, and open Fate. Exploration traverses its possible histories; production shapes the routes worth keeping into finished visual novels that make you feel what a choice costs.
Decide · Scenario
Meet the fork before it resolves. You make the commitment; the Domain derives what follows and records what changed.
Read · Experience
A replayable visual novel with finished text and images, many routes, and many endings. The dedicated reader is specified, not shipped.
Wander · World
Return to a branch at any hour and explore from inside what its people knew then. World remains an experimental, metered medium.
The instrument beneath it
A Domain holds the world together. Even before it becomes a novel.
Today, the same foundation can maintain a real situation for research and judgment. In Maya's climate-company decision, the grant, cofounder, runway, and commitments remain part of one changing world.
- Research keeps it currentSources and news enter one attributable evidence trail.
- The Domain keeps the worldActors, rules, resources, relationships, and commitments stay connected.
- The Graph traces consequenceEach change remains linked to what it affects and what stays open.
- Scenario opens the forkA move can be explored without erasing the world it began from.

The runway changed, not the ambition.
A possible cofounder can only commit part-time. A grant extends the earliest runway, while a lease renewal compresses Maya's decision window. The question is no longer simply whether to leave; it is what must be true first.
“I can commit two days a week until the grant decision.”

The world computes. You commit.
Scenario turns an open question into a situated choice. Take a seat, act on what that perspective could know, and let the branch preserve what followed. Episode is the deeper roleplay form in development.

The Domain changed: the grant improved runway; part-time help weakened execution capacity; the lease shortened the decision window.

The Graph connects sources to System, World, and open Fate, so every route can show what changed, what it cost, and which possibilities remain.

Beyond the novel · Experimental World
Walk any hour. Meet the world from inside.
A mature branch may become a place: return to a chosen moment, move through what was true then, and speak from inside its information boundaries.
World remains experimental, not a shipped MMO. It generates as you wander; persistent simulation, economies, institutions, and large populations remain research questions.
