Warhammer Online released an overview about the realm Norsca. You can get the details below.

Norsca is a forbidding realm of rocky hills and dark, overgrown pine forests haunted by long winters that blanket the land in perpetual frost. Though the jagged mountains and deep forests of ancient pine are a daunting challenge to men who would settle this cold northern expanse, the woods, rivers and bays of Norsca are rich with resources that sustain the hardy people who dwell there. Within the borders of this vast wilderness is a bountiful harvest for the many traders, trappers and fisherman that journey from the more civilized lands to the south.

In the eyes of most citizens of the Empire, Norsca is a wild and untamed land, full of dangerous creatures both natural and unnatural. Perhaps this is true in the deep north, but along its southern borders where Norsca joins with the northernmost provinces of Kislev, a civilizing influence has taken hold. Here, brave adventurers and resourceful frontiersmen who don¡¯t feel at home in the cities and towns of the south cross the border into Norsca to find their fortune. Towns, villages, and isolated farms are scattered across the rugged landscape, and though their residents lead a hard life, they are largely happy in it.

 For all the settling influence of civilization however, the dangers for which the land is known are quite real. In the northern reaches, barbarian tribes and followers of Chaos are numerous, and their raids frequently strike deep into the southern regions of Norsca. The residents of the villages here sometimes forge pacts with these tribes, intermingling and opening themselves to the influence of the Dark Powers through their alliances. Thus, even the most civilized of Norse are not to be trusted by righteous men.
