Ice covers probably about 90% of Belsavis's surface. The playable areas on Belsavis are tropical canyons between ice shelves or even under them in some places. Did you never see Belsavis from orbit or your galaxy map? I understand if you never read about the planet. Here's the Holonet page for the planet: http://www.swtor.com/holonet/planets/belsavis
