Where, exactly, do tauren come from? Yes, there's the old standby about a mommy tauren and a daddy tauren -- but in a world where some beings trace their origins back to stone constructs and ancient curses while others are native and still others were altered by the Well of Eternity, the question of where a people originated can be an important and convoluted one.
The most recent Ask Creative Development thread from the official forums managed to cover a lot of subject matter, from Elune and her relationship with the Naaru to whether Forsaken priests could actually blow themselves up by channeling too much of the Holy Light. But the question and answer that most interested me was the following:
Anne already discussed this to a degree, but I wanted to take a longer look at the tauren, their history and mythology, what they seem to believe about their origins, and why it might matter to this question. Where did the tauren come from?
Please remember the rules. This is all speculation, and while I try and build it on the framework of the lore we're supplied in game, I'm going to end up somewhere that is absolutely not at all in game.
