I used the map editing tool called World painter which is an amaizing program and you should check it out.
The map is a flat bedrock slate floating in an infinite void. You start off with only a single tree and lava and water which is in skyblock survival. This is much more difficult then the skyblock survival which i took inspiration from as it has much more mob spawning even during the day due to slimes. Friendly mobs are rare and if you go to far away from the spawn you arrive at a infinite void with no land. This map should be played on multiplayer for the best experience.
