Minecraft Zelda Dark World Mod idea: You can find a dark world portal tile very far away from spawn. walking over it takes you to the dark world. you can find a broken down temple that going to that same location in the dark world takes you to a complete version of the temple that holds the magic mirror that lets you create portal tiles anywhere you want. the dark world works by copying everything from what the overworld looked like when first created, meaning anything you changed in the light world (overworld) won't change in the dark world. every structure now looks different, now they look like a dark world counterpart like in the original game "The Legend of Zelda: A Link To The Past". I don't know about making a nether portal in the dark world, I'm probably just gonna stick to it just taking you to the regular nether, or just making it where you cant light a nether portal in the dark world. The Stronghold is a whole other topic, I have NO idea what to do for it, maybe it could lead you to a secret boss battle for a secret weapon. anyways this is a cool idea I had.
