Worldborder

So this server is a bit different, it currently has a Worldborder out at 20,000 blocks Overworld and Nether but no limit in the End. The Worldborder will expand based on events that happen in the server, if there is a lot of war and chaos than it may trigger a border expansion allowing more land to be discovered. But if it's very peaceful, it's unlikely the border will change, if the border does ever expand once or multiple times it will never shrink to a prior size, only expanding. Never shrinking.
