This map was made by taking a large chunk of netherrack and using tnt to hollow it out and give it a sort of natural feel. when it was shapped the way I wanted it to be I added Soulsand, Netherwarts, Lava River, a Bridge, and a nether tower that has a secret branch of rooms inside it. Note This is not automatic and is just a arena for a server with a Mob arena Pluggin. I am not including the world or schematic here because I want to see where my arenas end up at, so if you're intrested in adding it to your server leave a comment and we can work something out.
