This contains a 640x640 nether-like map. You may ask "I can just go to the nether for that" but think again. This map is different and better then the Nether in multiple ways. For one, it contains vanilla ores. It also is completely flat (And no ghasts spawn and kill you). Massive cave systems open to the surface. The map is surrounded by a lava ocean Then you might say but I like *** about the Nether. You can have that too, because the actual Nether is only a portal away.
