The movie, made in Finland, draws on old legends of a pre-Christian Santa Claus. And he ain't a nice guy. In the movie, Santa was buried in the ice and was recently dug up. Then the children started disappearing. According to reviews the film has a dark humor all its own.
When I read the review I immediately thought of this as a scenario for Barbarians of Lemuria. It fits the sword and sorcery genre perfectly. An ancient evil is uncovered and begins preying on the people of the area. The heroes have to track it down and face its unfathomable horror.
I wonder if I can pull this off.
