Master Nguyen

Master Nguyen is one of the five sorcerers that are found around Pandaria. According to Master Nguyen, the sorcerers have been wandering since the days of Lei Shen, passing the secrets of their order from generation to generation. He will not tell you what the secrets are and he does not know where the other sorcerers are as he no longer remembers. He says that they may very well be dead or may have been replaced by their pupils.

Also, he has the buff and has an air of electricity around him at all times.

Trivia

 *  might be referencing to ancient eastern mythology where there are five guardians with four each representing the different elements and one representing the earth. Considering he can be found at Windspire Bridge and there being four major temples and his storm buff, this is very plausible.
