evercrest's campus is quite large, even inside the walls. have lunch in one of the gardens or explore vendors in the courtyard on weekends. just don't get caught in a snowstorm; you might be buried in the snow and die without anyone knowing.
outside the outer walls of campus, there are many places to explore. not all of the ruins were renovated when evercrest was founded, so there are plenty of ruined buildings to explore outside the campus grounds. be sure to pack warm, though; once you get out of the protective atmosphere charm around the campus, it gets real cold real quick.
the great library is the second-largest library on campus. the largest is in the alchemists' tower, but the great library still has just about anything you'd ever want to read on its shelves. just be sure not to take a book out of the library, you could be expelled for that.
the warden forest is a relatively new forest full of young hardwood trees. it's planted a half mile from the campus proper and is kept alive by the atmosphere charm around the campus; however, the spell is thinner around the forest, which makes it colder than the rest of the area affected by the spell.
