Frost Ravens
From Wulfgard Wiki
The Frost Ravens are one of the most savage tribes in all of Northrim. A nomadic people, they move from place to place, hunting and raiding to stay alive. They rush into battle armored in little more than fearsome warpaint, wearing black raven feathers. It is said that they use some kind of spirit magic to break the will of their enemies, for the sight of their screaming horde sends fear straight into one's heart like a knife. Other tales speak of darkness following them, of their blades being colder than ice, and of their shamans transforming into flocks of ravens. Sometimes they perform night raids, clad all in black with black-painted shields, moving without the light of torches.
They are currently led by Guntram Frost-Raven, who utterly despises the Achaean Empire.
