Warlords of Draenor: Where is OUR Yrel?

After thinking about the specifics behind the upcoming Draenei hero Yrel, I stumbled onto a question that may have been asked already but was curious if the developers could shed some light on: do WE have Yrel too?

From my understanding, the inhabitants of this new Draenor are not new characters but simply existing individuals who followed a different path as a result of Garrosh's manipulation of the timestream. If this is true, would this not imply that the Draenei known as Yrel also existed or still exists in our proper timeline?

Is this the case? If so, is she currently alive or dead? If alive, what has she been up to and would we see any development of her?
