## Landwalker demo
An implementation of a landwalker server is located in `server/`. This includes a functional login server and a dummy shard (supporting the minimum amount of packets necessary). The DB implementation in `core/db/` matches the OpenFusion 1.4 SQLite tables, which the login server located in `server/` uses. There's no support for NPCs nor other players, and is liable to softlock the client.
