Since the dawn of Asgard, since the ancient times of Buri, there has been, and indeed always will be, a great book of kings. Written, and read, only by them. And within its infinite pages, you will find the stories of Ginnungagap, the great nothing that birthed the threads of creation… and from them, the weavings of damnation. Tales of death and rebirth. Of Ragnarok and resurrection. Of love and power, of winter and lightning and thunder and blood, of titans. And of war. Of gods and man and monsters… and the myths… that they have all made real.
From – Thor Vol. 6 #8
