This mod removes the void, making you safe from it. If you ever fall in it, you get teleported back up. If you are in a big hole or in a trap, don't worry, because after 3 times you fell in the void you get teleported randomly in a 1000 blocks range within the hole and your fall counter gets reset. You can use this in servers or in singleplayer, maybe to feel a little safer when looting End Cities in the End.
