I have gone to the beyond and I am faced with this

Any ideas how to regen? I've flown 2,000 in all directions and no land.

please help.

It is a void, it's meant to be, you can base there for more FPS if you want.

But its like that 1,000 in all directions and I went down until I dies and up to y:100 and its all like this, I thought I had to find and mine stuff from there?

nope, just build out from your teleport pad
