Of course.
Westeros is a continent made up of seven (IIRC) kingdoms.
* The North: here you find the Wall, where a number of black-clad rangers guard against incursions by wildlings (barbarian tribes) and Others (undead regenerating wights) from even farther north. There's some rumors of what seems to be an elf-like civilization in the north, too. Some of the barbarians are wargs, a sort of mystic warrior able to put their minds inside a wolf's body.
Here you'll also find the castle of Winterfell (home of the Stark family) and the Isles of the Ironmen, which seems (to me at least) to be a vaguely Viking culture.
* The Midlands: this is mostly a narrow bridge between north and south. It's a marshy land, where several rivers converge. The Freys and the Tullys are the main noble families in this area.
* The South: here you find the great kingdoms of Westeros, ruled by a number of noble houses which constantly bicker and squabble and war with each other. The most major of these is the Lannisters and the Baratheons.
Oh, and I didn't mention: there's scarcely any magic in Westeros, except for a few individuals. That seems to be changing as of Book 2 in the series.
Far off to the east are exotic lands that seem to be vaguely akin to Asia. These lands are much more magical than Westeros. Necromancers, priests, assassins, etc. There's a number of free trading cities, too, and also a vaguely Mongol-like horsemen culture. Daenerys Targaryen, who's the last member of the family that used to rule Westeros, wanders these countries. She has with her the last three dragons that exist.
Hope that was enough.
