Outer Wilds
The Outer Wilds, often referred to as the “outside” is a pseudo-dimension featured on the A Realm Recrafted SMP server. It's not an actual dimension, as it is found 20,000 meters/blocks from (0,0), beyond the red borders of the Overworld, and thus generates identically to the rest of the world. It is also found in the Nether and End, at 7,500 and 3,000 meters respectively. It functions as a place to freely gather resources and explore without fear of destroying any landscape in the Overworld. Since it's only designed for resource collection, all chunks located in the Outer Wilds are reset daily at 6AM (UTC+1). This keeps its size small and renews resources.
Entering/Exiting
A player can enter and exit the Outer Wilds simply by passing through the red border. Return trips can be made easy by installing a Lodestone or Waypoint Hub near the border. Be careful not to place either block beyond the border, as they will be destroyed the next morning with no way to get them back.
