That's a good plan.
Hopefully there's a big ocean somewhat nearby that 13topia can be moved to* without crowding anyone's skyline (sorry bobsky!
). That can wait 'til we explore a bit and settle on a base area like you say though. Fun!
* It looks like it's ~1MM blocks from water level to bedrock and would be less above since I haven't finished the upper sphere, so hopefully it won't be too much server strain to transplant it in 2 jumps.
