Odin (narration): Once, mankind accepted a simple truth, that they were not alone in this universe. Some worlds man believed to be home to their gods. Others, they knew to fear. From a realm of cold and darkness came the Frost Giants, threatening to plunge the  mortaI world into a new ice age. But humanity would not  face this threat alone. Our armies drove the Frost Giants back into the heart of their own world. The cost was great. In the end, their king fell. And the source of their power was taken from them. With the last great war ended, we withdrew from the other  worlds and returned home to the Realm Eternal, Asgard. Here we remain as a beacon of hope, shining out across the stars. And though we have fallen into man's myths and legends, it was Asgard and its warriors that brought peace to the universe.
