Azeroth is the world name where Warcraft series and World of Warcraft stories mainly occur. Azeroth's world is home to many races, the most famous of which are elves (night elves, high elves, blood elves), humans, goblins, trolls, dwarves and dragons.
Ner 'Ozu is one of the most complicated figures in the history of Warcraft, which is mainly divided into two stages: the orc shaman and the Lich King, so this is also the longest piece of character data (the Lich King is a part of the natural disaster of the undead). If you are interested in the history of orcs and natural disasters, don't miss the opportunity to learn about this character.
Naiozu is Gourdain's mentor and the oldest shaman in Delano. Demon Kilgardan took a fancy to this and decided to control the clan of orcs with Ner 'ozu to prepare for the second invasion of Azeroth by the Burning Legion. As a small reward, Kilgardan promised that Xiaonai would get great energy from it.
