Nortre Nui was first found by an ancient spirit called Nortre,believed to be the last of the Great Beings.The city was supposed to be wonderfully beautiful,but Makuta from all over the universe have come here to search for their true leader,who's name has been forgotten,but everyone calls him "Master".Any Makuta that happens to come to Nortre Nui gets trapped on Kraakhan Mound by a strange energy source,called "The Authority" by the locals.
