Muyoh is a level 20 elite tauren who is friendly to all players regardless of the player's faction. Pre-Cataclysm, he did not have a name and was just called Disciple of Naralex. Muyoh is one who has remained uncorrupted (it seems that there are no tauren among the ranks of the Druids of the Fang) within the Wailing Caverns. Once you enter the instance, he is the first thing you'll meet. He informs you that Naralex has gone to sleep. Naralex's dreams then became nightmares, which is the cause of so many deviate creatures appearing in the Wailing Caverns. However, he can't wake up Naralex and end his nightmare until the four Fanglords are defeated. Thus, he asks you to eliminate the four leaders of the corrupted druids.
