In 709 AD, in the Iron Age, a spacecraft crashes in
the Viking kingdom of Herot, Norway, and the pilot
Kainan survives. He turns the beacon on; learns the
language and culture of the planet using a machine;
and finds that the predator, Moorwen, that he was
transporting, had escaped. While chasing the alien
monster, he finds a village completely destroyed
and is arrested by the warrior Wulfric, believing
that he killed the locals - Kainan is brought to
Herot as a prisoner.
