Rundale
An Irish Living World Text Adventure, set in 1820 rural Ireland; powered by the custom Parish engine. 1820 was chosen as it in the middle of the period after the Acts of Union 1800 that brought Ireland into the United Kingdom of Great Britian and Ireland, and prior to the Great Famine.
The player arrives as a newcomer to Kilteevan Village, about two miles south-east of Roscommon town in County Roscommon. The village and surrounding area is populated with numerous non-player characters. NPCs are driven by LLM inference. A cognitive level-of-detail (LOD) system simulates NPCs at varying fidelity based on proximity to the player. The geography is based on real early 19th century Ireland. The characters and establishments are fictional.
Ways to run Parish
Four binaries built from this workspace, each with a single job:

subgraph Engine["Parish engine (parish-core composes 8 leaf crates)"]
Core[("game loop · world · NPCs · inference · save store")]
end
Repl["**parish-engine --headless**<br/>stdin/stdout REPL<br/>(also `--script` batch)"]
Tauri["**parish-tauri**<br/>desktop app<br/>(Svelte 5 UI + Tauri IPC)"]

| Binary | Mode | Has engine in-process? | When to use |
|---|
parish-tauri | just run | yes | Default desktop experience — full GUI. |
parish-engine | --headless (just run-headless), --script FILE | yes | Single-process terminal play; deterministic --script runs drive the test harness. |
parish-server | --port PORT (just web) | yes (one engine per cookie session) | Multi-user web server; serves the same Svelte UI; the target for parish-client, MCP, and browser sessions. |
parish-client | single-shot / --script / --json / REPL (cd parish && just run-client) | no — thin shell | Drive a running parish-server over HTTP. Use from scripts, CI, or as a lightweight terminal alternative to the browser. |
parish-mcp | MCP server (bash parish/scripts/parish-mcp-backend.sh start) | no — bridge | Expose mcp__parish__* tools to AI agents (Claude Code, etc.). Also bridges over HTTP to a running backend. |
Shared rule: mode parity. Every gameplay feature behaves identically across Tauri, headless, and web. Shared orchestration lives in parish-core; entry-point crates contain only thin wiring (see docs/agent/architecture.md).
