So I built a obsidian room very close to the spawn and it was meant as a sort of a jail. im not sure how the command works but I think we could go somewhere with this...

actually i moved it to a place called chateau. i would post a screenshot but im not to sure how, so look at bayvillage, find the desert above it, and move to the right, its a small bedrock structure on a cliff overlooking a desert,ocean,,fields and an ocean

and a forest, not a second ocean
