Nether Lock prevents players from accessing the Nether by automatically destroying any Nether portal blocks as soon as they are created. Players can still build portal frames out of obsidian and attempt to light them, but the portal will immediately break before it can be used. This addon is useful for survival worlds, challenge maps, custom game modes, servers, or realms where you want to completely disable Nether travel while keeping the rest of the game unchanged. It works automatically in the background, requiring no setup or commands, ensuring that the Nether remains inaccessible until the mod is removed
