I'm a canon junkie. I admit it. So I voted whatever the 5e continuity says. Mainly I think I'm this way because I love incorporating whatever the latest thing off the presses is into my game. In 3rd edition, the shade invaded my game. 4th I ran a short campaign in the area around Aglarond (to keep it close to Thay, which I love). In 5th I've started on the Sword Coast to take advantage of the current published adventures until a full campaign guide comes out (or we get more information on what is happening across the realms).
