Build me a around 100 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
