# 仙剑奇侠传 / Sword and Fairy (nitan170911)

> slug: `nitan170911` · browser status: `playable` · native port: `40018`

The root of this collection's entire NT/nitan/Lonely engine lineage — sibling libs like xfbhh, hhsj, and nt1 all descend from it — and its largest member at roughly 54,600 files. Set in the world of the beloved Chinese Paladin / Sword and Fairy (Xianjian Qixia Zhuan) game and TV franchise, it shares its core F_DBASE attribute-storage architecture with smaller sibling nitan6 (Laughing in the Wind). Its account system depends on an external MySQL server for cross-site character roaming, so in this archived environment new registration is gracefully declined with an in-fiction message rather than broken — it's best explored by browsing the code and world content rather than played start to finish.

## 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 `nitan170911.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/nitan170911/`).
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 `127.0.0.1:40018`.

- 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.
