User:LinkGanonSlayer9/Minecraft Lore/World Border

The World Border was a ethereal barrier set up by the Mojang gods. It separates the inhabitants and main world from the cursed, airless area of the world. This was formed after Herobrine casted an eternal curse on the World, and the gods and goddesses had to set up the barrier in order to protect mankind from the effects of Herobrine's curse. To prevent anyone from recklessly entering the cursed exterior, it was made solid towards living beings as to disallow anything inside to pass through; however, flora is still able to somehow thrive inside and liquid can still flow past.

Outside
The area outside of the border is a continuation of the inside, except completely airless, which results in people suffocating inside.
