just done my portal and it looks pretty cool do i need to make another one in the nether or will there be one there for me to get back?
Another portal will be created in the Nether, but there's a good chance that when you use that portal to exit the Nether it will create a seemingly random third portal, so be prepared for that. The first time that I exited the Nether, I ended up in a small dark cave and when I dug up to find where I was, I found myself under the sea about 100 meters from my original portal. I had to spend the next half-hour fixing the alignment.
