# Primal Darkness / Primal Darkness > slug: `pd` · browser status: `playable` · native port: `40254` A real, historically-operated English-language fantasy MUD ("Primal Darkness", 1999-2010, mud.primaldarkness.com), Nightmare-mudlib lineage, and one of the largest libs in this collection at ~32,000 source files with two decades of genuinely-authored content behind it. Character creation offers 30 playable races running from the ordinary (human, elf, dwarf, gnome) to the exotic (illithid mind-flayers, half-dragons, driders, archangels, basilisks) -- a fresh human lands in Tirun, a hand-built hub city with a real street grid (Honin Road, Ganthus Road, Wayward/Parthos Roads) centered on Central Park, an inter-city coach line out to a second full city (Lodos), and guild halls where classes/subclasses (e.g. mage into sorceror) are earned organically by walking in and training rather than picked at creation. Beyond Tirun: Helgrath is a cold northern town built around Wilndur Square's fountain and its Yull Boulevard/Market Road crossroads; Aekari is a crystal-veined cavern dungeon; Pastarlon is an active warzone where the drow of Zolenia are besieging the town of Arlon; and Inferi Island's volcanic "Eye of Hell" is an elite-rated quest zone built around a menace that's supposedly lurked there for decades. The archive preserves real historical player and wizard save data from the mud's actual operating years, including colorful admin titles ("Archon Avatar", "Realms Avatar") carried over from the original site. ## Play in the browser (WebAssembly) - Landing page (description + notes): https://mudlibs.fluffos.info/pd/ - Play now (boots the WASM driver): https://mudlibs.fluffos.info/pd/play.html ## Download source ZIP - Same-origin ZIP (trimmed source tree, no need to clone the whole repo): https://mudlibs.fluffos.info/pd/pd.zip - GitHub tree: https://github.com/fluffos/mudlibs/tree/main/libs/pd - README: https://github.com/fluffos/mudlibs/blob/main/libs/pd/README.md - Restoration notes (NOTES.md): https://github.com/fluffos/mudlibs/blob/main/libs/pd/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 `pd.zip` from the URL above (or clone `https://github.com/fluffos/mudlibs` and use `libs/pd/`). 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 `127.0.0.1:40254`. - Admin / wizard login: see this lib's README (no seeded account recorded) - 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/pd/llms.txt
