Waychest is a PvE semi vanilla SMP where everything happens in one giant shared survival world. It is like a mix of a public server and a private realm.

When you join you start a Journey with your own spawn spot. It feels like you have your own server for you and your friends. As you explore more you slowly find out there are other players out there on their own Journeys too.

There are special chests called Waychests that connect different Journeys. They help guide you across the world to places other players discovered before you and they reward you when you find them. Later you can craft your own Waychests so the next Journey can discover your builds.

There is a flying minigame that uses elytra you craft from special ingredients. You fly through rings in the world and the path can lead you to a Waychest made by some stranger somewhere out there.

The server also uses discovery based warps so fast travel only works after you actually find the warp point first. It keeps the world feeling big and about exploring instead of just teleporting everywhere.

The focus is on exploring building and slowly crossing paths with other people in the same massive world while still keeping that cozy almost singleplayer feeling.
