A browser-based living world simulation where civilizations rise, fracture, migrate, starve, worship, fight, remember, and evolve.

AEON is an experimental living-world sandbox. A fast, deterministic simulation runs the terrain, climate, ecology, cities, economy, and wars; thousands of real, persistent citizens live inside the cities with personalities, memories, beliefs, and grievances; religions and factions emerge from those beliefs and go on to schism, spread, and overthrow states; and an optional local LLM acts as a world-spirit that bends the rules (never the outcomes) and narrates the unfolding history into a Chronicle. You watch and steer it all from a real-time 3D dashboard built mobile-first.

⚠️ This is an experimental prototype, not a finished game. Sim balance, AI systems, and save formats are all evolving. The goal is a world that becomes stranger, richer, and more storied over time — one you open "for five minutes" and look up three hours later, invested in a fictional dynasty. See Known Limitations.

AEON couples a deterministic Tier-0 simulation (the source of truth for every outcome) with optional higher "intelligence tiers" that only interpret or nudge that truth:

• The sim (aeon/sim/) owns terrain, climate, resources, species, civilizations, cities, units, and events. Same seed + same config ⇒ the same world, every time.
• Citizens (aeon/agents/) are a level-of-detail persona pool — only people near your focus fully materialize, so the world scales.
• Society (aeon/society/) grows religions, factions, and cultures from real citizen beliefs, and writes the Chronicle.
• AI/minds (aeon/ai/, aeon/mind/) are prototype learning systems: per-species policies that learn from how their people fare, and a teacher→student "society mind".
• A local LLM world-spirit (aeon/governor/, via Ollama) is fully optional — if it's unreachable the world keeps running on deterministic fallbacks.
• The renderer (web/) is a Three.js/WebGL dashboard you open in any browser.

See docs/ARCHITECTURE.md for the full picture.

• Procedural world generation — terrain, climate, biomes, rivers, resources, wildlife; fully seedable and deterministic.
• Multiple civilizations — the world opens as several distinct rival nations (default 5), each with its own archetype: ideology, economy, war, and expansion bias.
• Cities, citizens, factions, religion, migration, war, economy — a living social stack where towns grow, trade, starve, rebel, convert, and conquer.
• Living history timeline — a Chronicle of foundings, wars, schisms, golden ages, famines, and collapses.
• Species/citizen AI systems (prototype) — per-species learning policies + a teacher→student "society mind".
• Real-time 3D browser renderer — day/night, normal maps, IBL, bloom, sim-driven night city-lights, LOD, instancing, frustum culling, quality presets, perf HUD.
• Texture packs — switchable visual themes (medieval, ice age, volcanic, desert, lush, dark fantasy, …). See docs/TEXTURE_PACKS.md.
• Restart / New-World controls — restart from zero, same seed, random seed, custom config, or reset a single layer (civilization / terrain / cities / minds).
• Editable worldgen variables — seed, size, civ count, climate, water level, resources, wildlife, war/tech rates, and render budgets, all from the UI.
• Save / load — sqlite-backed world saves carrying the full generation config.
• Charts and dashboards — population, civilizations, economy, and history overlays.

# 1. clone, then from the repo root:
uv venv --python 3.12 .venv          # PyTorch needs Python ≤ 3.12
uv pip install --python .venv/bin/python -r requirements.txt
# 2. run
source .venv/bin/activate
python -m aeon                       # serves the dashboard on http://localhost:8080
# 3. open http://localhost:8080 in a browser

No GPU and no LLM are required — AEON degrades gracefully (numpy policies, an offline "spirit"). Full install + troubleshooting: docs/INSTALL.md.

Exact, verified steps for Fedora/Linux and generic Linux are in docs/INSTALL.md. Summary:

• Python 3.12 (PyTorch has no 3.14 wheels) + uv (or pip)
• pip install -r requirements.txt
• Optional: an NVIDIA GPU + CUDA (GPU-accelerated policies) and a local Ollama server (LLM world-spirit + narration)

python -m aeon        # or ./run.sh

Then open http://localhost:8080. Details + troubleshooting (port in use, blank screen, resetting saves): docs/RUNNING.md.

Time controls, overlays, camera modes, panels, and the perf HUD (P) are documented in docs/CONTROLS.md.

Boot config is config.yaml (override the path with AEON_CONFIG). Per-key reference: docs/CONFIG.md. Editable world-generation variables and the New-World / restart system: docs/WORLDGEN.md. Sample configs are in examples/configs/.

Switchable visual themes built from the bundled CC0 texture library. See docs/TEXTURE_PACKS.md and web/assets/texturepacks/.

source .venv/bin/activate
python -m aeon                       # run the server
node --check web/js/*.js             # JS has no build step — syntax-check this way
python -m pytest tests/ -q           # the test suite
bash scripts/check.sh                # compile + tests + JS syntax in one shot

More in docs/DEVELOPMENT.md.

python -m pytest tests/ -q

The suite covers determinism, restart, world-config validation, building placement, save/load, the species-mind policies, and the API. scripts/check.sh runs the whole verification sweep.

AEON is an honest work-in-progress. Read docs/KNOWN_LIMITATIONS.md before forming expectations — sim balance is experimental, AI systems are prototypes, performance depends on your browser/GPU, and save compatibility may change.

Staged milestones (M0–M8) are in docs/ROADMAP.md; the longer design vision is in ROADMAP.md.
