# 天下 Beta / Tianxia Beta (World Under Heaven)

> slug: `tianxia` · browser status: `playable` · native port: `40044`

Self-titled "Tianxia (World Under Heaven) Beta," credited to an author known as "Discovery No. (Find@tx)" — from the same author as this archive's "Nitan" series, though built on a completely independent codebase, and by its own in-game text still an early, actively-changing build ("regularly modified and added to"). New characters freely distribute talent points across six attributes (hand-adjusted within limits, or rolled at random), and are then sent by their "master" to Bamboo Courtyard (松竹小院), a quiet retreat where an NPC page-boy formally hands over a welcome handbook — a small deliberate piece of roleplay ceremony rather than a bare stat dump. Chinese names may not begin with "Tang" (唐) or "Treading Snow" (踏雪), reserved because the game has its own in-world Tang Clan (唐门) faction; wizard accounts are additionally held to a stricter password policy (10+ characters, mixed case plus a symbol) than ordinary players.

## 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 `tianxia.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/tianxia/`).
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 `127.0.0.1:40044`.

- Admin / wizard login: `fluffos` / `Mud@2026Admin`
- If you host this on a public network, change the published default
  admin password before opening the port.
