Ride to Valhalla! Protect the man and Gods from the Hrimthursar and Jotuns, and beware the creatures of the ice and fire! In the dark night, when snow is slowly falling, far away in the Jotunheim, Frost Giants called Hrimthursar are sharpening their weapons, and dreaming about conquering Asgard, Midgard, and all other worlds, where they will bring frozen winds and darkness.
