Many of the questions that have had players mystified since Warlords of Draenor was introduced last year at BlizzCon surrounded Draenor itself. How did it appear? Why is it different? Why don't the events that occur on Draenor have any kind of bearing on what's going on with Azeroth? If Draenor is an alternate Draenor, is there an alternate Azeroth as well? Does this mean there are duplicate lore characters? Will we see two Thralls, two Velens, two versions of Garrosh? And as the year has slowly marched on, that question has been answered in bits and pieces, but never with enough clarity to really set people's minds at ease.
When the Warlords of Draenor beta was released, it became immediately clear to anyone that knew the history of Warcraft that this Draenor, the one on which we are going to be building garrisons, amassing armies, and defeating the Iron Horde, is not and never was the Draenor we were already familiar with. It's an entirely different planet. We've been using the term "alternate universe" in reference to Draenor because seems the best term to encompass the concept of this strange world. With the release of the short story Hellscream, it has finally been made clear just what is going on with Draenor -- and it has nothing to do with Garrosh's trip, and everything to do with the Bronze Dragonflight.
Please note: The following Know Your Lore contains several spoilers for Warlords of Draenor as well as the short story Hellscream.
