how can i use this map? i just tried to start a new game in a custom word but i dont see the map on the list.

I whanted a map were the castle would be a bit higher than the city but in parts of the city there a big ditch (holes) where the poor slums would live in and farmlands outside the castle wall a tiny bit lower than the main city but i never had the skills to use the voxel tools also the city would be completly falt some parts would be sligly raised and such i hope this makes sences thanks

I wanted to try to make a ravine-style map that would be great for mining in survival. I would like to see what you can make of it :)

Have an idea for a map? let me know
