The X-Files, Season 2

Scully:
I found a children's book of Norse legends. From what I can tell, the pictures show the end of the world - not in a sudden firestorm of damnation as the Bible teaches us, but in a slow covering blanket of snow. First the moon and the stars will be lost in a dense white fog, then the rivers and the lakes and the sea will freeze over. And finally a wolf named Skoll will open his jaws and eat the sun, sending the world into an everlasting night. I think I hear the wolf at the door.
