World Bound
by AphernixMC
World Bound is a Fabric minigame in which the playable area keeps shrinking while a player works toward a goal such as slaying the Ender Dragon.
What it does
Once a match starts, the world border closes in on the center at a steady pace, so a player has to gather resources and move inward before the border reaches the base they built. The goal stays the same as the arena gets smaller, and the stakes rise with each passing minute rather than being eased. Slaying the dragon before the world disappears is the main objective, and it takes place on the same map the player has been exploring.
The minigame leans on time pressure more than on long exploration. Finding a stronghold means gathering enough Eyes of Ender while the ground beneath the feet is already vanishing, so routes and timing matter as much as combat. The mod is server-side only, so players join without installing anything, and the server owner runs the match. It is published for Fabric, with the latest build 1.0.0 for 1.21.9, under the MIT License. It is not open source.
Installation requires the server side only. Snapshot builds are not published, and the author has not listed other loaders.
Key features
Closing world border
The border shrinks toward the center over time, and the playable area gets smaller while the player keeps working.
Dragon goal
The match is won by defeating the Ender Dragon before the world has shrunk away entirely.
Stronghold search
Players must gather Eyes of Ender to locate the stronghold while the outer area disappears around them.
Fixed objective
The goal does not change as the arena shrinks, so the pressure comes from the map rather than from new rules.
