Zen
This mod that adds teleport commands between the overworld and the end and adds three new dimensions.
Information:
The first dimension is similar to the way Hell looks but with no netherrack and with stone, ores, and trees. The top of the dimension is also able to be mined. There is mostly lakes of lava, but there are some water spouts here and there. Glowstone can also be found. There is also sun light once you reach the top and mine your way there.
The second dimension is the void with a one layer bedrock bottom for custom building, redstone, and command blocks.
The third dimension is completely blank to begin with. So you have to build from the base in order to have anything to walk on. Similar to the void however there are biomes and weather and plants grow normally and such.
