A band of wondering goblins shiver as the air around them is suddenly void of all warmth. Struggling against their bodies involuntary convulsions, they darw their weapons as a mysterious figure approaches. completely unaffected by the freezing temperatures, the lone warrior begins her assault on the unfortunant humanoids. All around them manifests a blizzard that hinders their movement and sight. As they struggle to move, the ice starts to encase their limbs.

With one fell of her mighty greatsword, the Knight shatters their frozen corpses, sending shards of glittering goblin across the tundra.

Rimed Soul
Frost Knights are warriors who underwent a special ritual as childred that infused their souls with the essence of an ice elemental. Surving this ritual and being able to harness the power is considered to be among the greatest of accolades a warrior can acheive, even though it is usually involuntary. Frost knights often hold contempt for their culture for forcing them to be what most people believe to be an abomination, a living bridge between the mortal and elemental realm that should not exist. Despite how society views them, Frost Knights are usually decent natured beings and have no qualms fighting a horde of monsters, single handedly if need be, to protect even those who look down on them. Many generals search out Frost Knights not only for their martial prowess, but also for their battlefield control capabilities. It is said that an extremely experinced and capable Frost Knight is even able to command the very forces of nature and create powerful blizzards. A feat many such armies would do anything to possess.
