Loki knew that his days in Asgard had come to an end. He knew how soon anguish can give way to anger and was sure the gods would avenge Balder’s death and detention in Hel.
He ran away. He made for a deserted part of Midgard, a remote place in the mountains at the head of a steep valley that fell into the sea. He found a hollow near Franang’s Falls and, using the rock and rubble lying all around, built a low house that no man was likely to see until he had stumbled into it. It had four doors so that Loki could keep watch in every direction.
Thor said Summer was the open season and he announced his plan of making a journey east into Utgard and flexing himself against the giants. ‘However few they are,’ he said, ‘they are too many.’
WHEN THOR AWOKE and reached out to grasp his hammer, it was not there. The Hurler leaped up. He tousled and tangled his red beard; his hair bristled as he searched for Mjollnir. ‘Listen, Loki!’ said Thor. ‘No god in Asgard has seen my hammer; no man in Midgard has seen my hammer: it has been stolen.’
THE NIGHT WAS ALMOST OVER; the sky was green and grey in the east, and snowflakes were ghosting around Asgard. Loki and only Loki saw Freyja leave Sessrumnir. Her cats slept undisturbed by the hearth; her chariot lay unused; in the half-light she set off on foot towards Bifrost. Then the Sly One’s mind was riddled with curiosity; he wrapped his cloak around him and followed her.
SOMEHOW THE SHAPE-CHANGER got into Sif’s locked bedroom. Smiling to himself, he pulled out a curved knife and moved to her bedside. Thor’s wife was breathing deeply, evenly, dead to worldly sorrows. Then Loki raised his knife. With quick deft strokes he lopped off Sif’s head of shining hair — her hair which as she moved rippled and gleamed and changed from gold to gold like swaying corn. Sif murmured but she did not wake; the hair left on her cropped head stuck up like stubble.
BEYOND THE GIRDLE of flint-grey water and the loveless lava flows, beyond the burning blue crevasses, lay Thrymheim, the storm-home of Skadi and her father Thiazi. It was a wonder that the hall withstood the charges of the wind and the batteries of hail.
