I look forward to seeing all the other worlds out there besides Avlis. For now, I've only been to Hala (and not even Hala 2). Hala 2 looks really awesome though when I was watching Kris wander through it. Looks much much better than the old Hala - though I do kind of miss the old Hala .... it had a certain charm to it.
The only thing I'm worried about is that is it easy to get back to Avlis once you portal through? I'm worried I will be lost forever if I visit the other worlds! Kris never did figure out how to get out of Hala 2 ...
