Build me a around 50 block radius nether hub that is in octagon or square shape, has a unique design with dark blue color pallete using sculk and pale oak for contrast. blue fire and sea lanterns as light. It should have 8 ways leading out of it as tunnels to fly out with an elytra and some sort of distinguishment which way is which. It should be mainly empty but hold a lot of detail and look majestic not empty. Do not make it too big. Make it like a hall but can be open on the roof. We want a central nether portal and actual flames and lanterns for lighting, not built flames. Just soul soil or soul sand with flames on top. It should be with easy obtainable blocks and not too detailed. It should have depth. A passable walkable way to each tunnel and fully surrounded by walls
