The year is A.D. 922. A refined Arab courtier,
representative of the powerful Caliph of Bagdad, encounters
a party of Viking warriors who are journeying to the
barbaric North. He is appalled by their Viking customs --
the wanton sexuality of their pale, angular women, their
disregard for cleanliness . . .
their cold-blooded human sacrifices. But it is not until
they reach the depths of the Northland that the courtier
learns the horrifying and inescapable truth: He has been
enlisted by these savage, inscrutable warriors to help
combat a terror that plagues them -- a monstrosity that
emerges under cover of night to slaughter the Vikings and
devour their flesh . . .
