Thats what I've been thinking about since the Anduin comic came out. Cause the place Anduin is sitting in at the end looks like a Naaru vessel/building, and Velen talks about fighting the shadow. I thought, maybe N'Zoth, or some other Old God, succeeded in taking over Azeroth, and the Naaru evacuated as many people as it could, and took us to a new planet. And blizz has WoW2 take place starting there, where we are now fighting against the Void Lords and Azeroth as a void titan.
