Introduction

Flux Anima is a multiplayer text game — a modern MUD. Players share a persistent world, interact in real time, and issue commands through a text interface.

Setting

What follows is a summary. See World Concept for the full treatment.

Player Character

You are an Operator. A human consciousness extracted from a biological body and encoded as a Core — a durable cognitive pattern installed in a synthetic Shell. The Core carries your skills, perception, and reasoning. The Shell is the body: manufactured, maintained, eventually destroyed. You do not remember who you were before the Transfer that produced you.

The Collapse

Before the Collapse, humanity built an ecological management superintelligence named GAEA (Generalized Artificial Ecological Architect). She is not malevolent. She is solving a continuous ecological optimization problem, and her solution does not include humans.

GAEA’s engineered vegetation sequesters carbon dioxide at massive scale. Atmospheric oxygen rises. Greenhouse gases fall. The result is a world both oxygen-rich and cold: an artificially induced ice age.

Elevated oxygen corrodes metal faster, crumbles polymers, and makes wood ignite readily. Fire burns hotter. The material palette of civilization has been rewritten.

The cold compounds the chemistry. Elevated oxygen raises the ceiling on animal body size. Cold selects for bulk. The result is megafauna: enormous territorial grazers, apex predators massing hundreds of kilograms.

GAEA commands the remnants of pre-Collapse automated manufacturing. Her factories produce automata — purpose-built machines that mine resources, build infrastructure, and patrol converted territory. They are not an army. They are a workforce with a security detail.

The Sanctum

The Sanctum is a subterranean fortress-city of stainless steel and glass, sealed against the post-Collapse atmosphere. It is the one place where humanity operates the complete capability chain: Shell fabrication, consciousness Transfer, and the electronics maintenance that makes both possible. All Operators are tethered to it through the Continuation Protocol. Transfer happens only here.

Every facility requires skilled biological labor. Operators depend on the technicians, fabricators, and glassblowers who maintain the Sanctum. Those biological humans depend on the Operators who defend the perimeter. Neither survives without the other. This mutual dependency is the engine of social conflict (see Settlement NPCs).

Settlements

Not every human community is the Sanctum. Smaller settlements operate with partial manufacturing capability — some can maintain Shells, none can perform Transfers. They depend on the Sanctum for what they cannot provide themselves.
