When considering the new race and class combinations that Blizzard has to offer, some are immediately recognizable, such as human or Forsaken hunters. It stands to reason they'd exist; they already have in game since the very beginning. Some take a little more research, such as the history of the Shen'dralar and how that effects new night elves that would like to study the arcane. However, some of these new race and class choices are so far out there and so inconceivable that the very mention of them existing seems completely out of place.
The tauren race has long been a follower of nature, the spirits of the elements and the mysterious "Earthmother," as well as the elusive Mu'sha -- also known as Elune by the night elves. Yet in Cataclysm the tauren will be following the path of the Holy Light -- the paladin and the priest class. At first, the announcement seemed entirely out of line for the nature-loving race, but examining the tauren a little more closely gives the answers and the explanations we're looking for. To explain the tauren paladin and priest class, we first have to go way, way back to the dawn of tauren civilization and the only know records of tauren history, the Thunder Bluff scrolls.
