The Void Dimension is a dimension that lives under the overworld and also in the end! but you can't just fall into the void and boom your inside it, you need to follow some steps, go to the end and then try to find a structure filled with black blocks and a netherite block, if you didn't find one go to the end islands and, look! it's there! when you go inside the structure you will find a spawner that spawns the zombies known as Shender Zombies, when you kill them they will give you a bedrock piece, when you have 9 of them you can craft them into bedrock or smelt them with 1, if you put 1 bedrock and 1 bedrock piece into the crafting table you will get the Void Advancer that is a new flint and steel (which isn't flint and steel, it's all bedrock) if you make a nether portal but instead of obsidian its bedrock take the Void Advancer, light it, and Boom! all the other complicated stuff are up to you to find! Hope you have fun!
