The Vikings vanished centuries ago, fleeing their crumbling homelands for shores unknown.
Those left behind were conquered by the Knights and assimilated into their cultures.
The Vikings returned in great numbers a few centuries ago. They came from far across the sea to where they have established a new homeland. They retuned for many reasons, but mostly to reclaim their ancient homeland in the North: Valkeinheim. Hundreds of Viking clans now coexist in relative peace in the frozen tundra. To the outside observer, however, they seem to exist in a state of perpetual civil war.
Vikings are the undisputed masters of the sea and fresh water. When this raucous nation gathers together in massive armadas of dragon-headed ships, they are fearsome to behold and nigh unstoppable.
