New dimension: The Ore Factories (DANGEROUS!)

The most Dangerous place in the game: the ore factories. to enter the dimension, you must light the portal in the middle of an ancient city, and the main mob that spawns is the undead (Maybe more lore about the mourners[Wardens]?). this would add a new use for smite enchantment. it would have loot chests with enderpearls (Good for speedrunners!) (very rarely) and raw materials at the beginning of a factory and processed materials at the end. maybe with the ender pearls chest (at the top of the factory where the boss would have been) theres also diamonds and emeralds. to light the portal to the ore factories dimension you need to use blaze powder (so it doesn't ruin the progression of the game.) did i mention it was dangerous? yes! there are piston squashers and air pollution all over! if you stand in the coal fires for too long you get poison II until you get out of the smoke! not to mention the hordes of zombies punishing the poor copper golems working the machines! they keep those golems in with lock and key (little walking golden and blue keys) which to get you need to punch onto your back where shulker backpacks go. to get them you cant be wearing a backpack, and you cant take damage. they keys are at the beginning and to get to the golems at the end you need to get through without taking damage! tunneling? watch out for the boss at the top of the factory; The warden wants to make sure those keys don't escape! it looks a bit different though... doesn't it?
