I want you to build me a sick-looking massive Nether hub base that will go on my Nether roof. I don't want you to use an abundance of random blocks. Keep it normal, but I still want it to look absolutely amazing, gigantic, and stunning. I want there to be a pit in the middle, not too big at all, that will have the bedrock broken to the bottom. I do want the center of the hub to have the main portal. Make the main portal grand. I want the entire build to be that of a Japanese demonic-style house with curved roofs and intricate details.
