Fairyland Online — WASM Client

Welcome, adventurer

This client runs the original Fairyland Online protocol entirely in the browser via WebAssembly — the Fairyland stream cipher, the three-server login→char→game handshake, asset decoding, and a click-to-move game view. Pick where you'd like to go:

🗺️

Enter the world

Connect, pick a character, and play. Click a tile to walk.

🧝

Create a character

Name, race, sex, appearance & colors. Sends CS_CHAR_ADD.

🧭

Map viewer

Browse the decoded map ADFs and ground-tile sheets.

⚙️

Quick self-test

Verify the Fairyland cipher round-trips in WASM.

Before you play

Browsers can't open raw TCP sockets, so the client talks to a thin WebSocket→TCP proxy that relays bytes to FOE (the proxy never decrypts). Start the proxy, then a static server for these pages:

# proxy
cd proxy && FL_UPSTREAM_HOST=foe.stole-your.net FL_UPSTREAM_PORT=4721 node ws_tcp_proxy.js
# web UI
cd web && python3 -m http.server 8000
