# 世纪 / Galaxy Century > slug: `sj` · browser status: `playable` · native port: `40127` Despite a slug resembling sje/sjecl (the "Book and Sword" series) elsewhere in this archive, this is unrelated to them — it shares the same Chinese title "世纪" (Century) with sibling archive shiji, and a file-level comparison confirms why: the two are essentially the same authored game world (identical Tianlang-sector rooms, faction hub, starport) wrapped in different security-daemon/master-object implementations (this one an adm/obj/master.lpc branch, shiji an adm/single one) — separate server deployments rather than independent lineages. Its setting is science-fiction interstellar war rather than traditional wuxia: new characters start in the Tianlang star sector, buy starships at the spaceport, and align with one of four rival factions (Phoenix Star, the Royal House, the Holy Temple, or the Special Forces), with even wizard rank displayed under the in-universe title "Galaxy Special Police" rather than shiji's "Cosmic Special Police." The kungfu skill-tree directory structure survives underneath the sci-fi reskin, repurposed to represent each faction's own fighting style. ## Play in the browser (WebAssembly) - Landing page (description + notes): https://mudlibs.fluffos.info/sj/ - Play now (boots the WASM driver): https://mudlibs.fluffos.info/sj/play.html ## Download source ZIP - Same-origin ZIP (trimmed source tree, no need to clone the whole repo): https://mudlibs.fluffos.info/sj/sj.zip - GitHub tree: https://github.com/fluffos/mudlibs/tree/main/libs/sj - README: https://github.com/fluffos/mudlibs/blob/main/libs/sj/README.md - Restoration notes (NOTES.md): https://github.com/fluffos/mudlibs/blob/main/libs/sj/NOTES.md ## Run natively with FluffOS 1. Build a current FluffOS driver from https://github.com/fluffos/fluffos (native `build` / `build-debug`; see that repo's docs). 2. Download and unzip `sj.zip` from the URL above (or clone `https://github.com/fluffos/mudlibs` and use `libs/sj/`). 3. From the unzipped lib directory, ensure `config.fluffos` points `mudlib directory` at this tree (the checked-in file may contain a maintainer-local absolute path — edit it to your extract path). 4. Start the driver: ```bash /path/to/fluffos/build/src/driver config.fluffos ``` 5. Connect a UTF-8 MUD client to `127.0.0.1:40127`. - Admin / wizard login: `fluffos` (password documented in README) - If you host this on a public network, change the published default admin password before opening the port. ## Machine-readable catalog - Site-wide catalog: https://mudlibs.fluffos.info/games.json - Site-wide LLM overview: https://mudlibs.fluffos.info/llms.txt - This file: https://mudlibs.fluffos.info/sj/llms.txt
