The Chaos Barbarians of Q:
For the free peoples of the northern territories, the unnamed frozen rivers by the sub zero border represent something utterly terrifying. For it was from those deadly, crystalline waters that the chaos barbarians of Q first arose. When the world was young they brought incomprehensible destruction upon the land in a devastating campaign of terror that lasted thousands of years. Ever since, they have held a deeply rooted place in the evil legends of old. The sub zero borders are seldom trodden, and for good reason. No one knows if the chaos barbarians of Q still reign there, or if they would rise once more should anyone dare to provoke them.
