I packed a way to get to it below, and look at that! is a house, probably some admin.

 

It's someones old base .-.

 

But, how? one admin right? cuz you cant put block there, cuz is spawn

 

That's been there for a while.

 

Is this skyblock?

 

Yes

 

Ik that place. It is under spawn i think

 

The lava place belongs to GreenCube5000, his shop warp is /Warp GreenShop
