This is a modded map which is called the Modded Dimensions map. You can play this map alone or check the map out with some friends. When you download this map you will spawn in the over world (normal minecraft dimension). But you will have two portals, one for the end and one for the nether. When you go into the nether you will be entering the “diamond nether” and when you go to the end you will be going to the “gold end” Basically netherrack has been modded to be diamond, and end stone has been modded to be gold. Enjoy playing!
