I had really no idea what to expect when I first went to Belsavis. When i discovered it was a prison planet, I wasn't expecting a lot, buy boy was I wrong! This planet is one of the prettiest and largest gaming areas I've found. I spent a lot of time exploring this planet, and I still didn't find all of the teleport areas. I believe I got most of the quest lines done, which I must say was also very well done for my class. The variety of mobs and quest styles on this planet is something to look forward to.
Here's a video tour, and some screenshots to wet your whistle below it.
