Let's delve into the past. It is the end of the Stone War. The only victors were the few Testificates from both sides that fled planet Minecraftia before the final bombs fell. Some fled underground, setting traps for all who dared follow.
The wasteland above is lifeless. It's only been a few years since the bombs, so it is possible to be above ground for some time without being irradiated, but the acid rain continues.
The radiation tore rifts in the fabric of space. This presents an opportunity to travel between dimensions, even sub dimensions. True magic, however, has been all but eradicated from this plane by the radiation. Still, it does look like something has happened to the plant life, and some stone. You will have to construct tools to survive.
