In this adventure, intrepid investigators are sent to the frozen wastes north of the Arctic Circle in 1943 to hunt for mysteries behind enemy lines in Norway and Finland. Resistance reports have alerted the British intelligence services to unusual activity - and the presence of a well-known German occultist - in the vicinity of the village of Trellborg in Finland.
After an outline of what is going on, the mission briefing is supplied in two versions: one for military characters (who could be the pre-generated ones provided) and one for non-military investigators - who will find themselves being sent on a crash course in winter survival, canoeing and Nordic skiing before they are sent on the mission. They also meet a mysterious specialist who will accompany them whose name is Seraph and who is indeed 'on the side of the angels'.
The adventure itself is a reasonably linear narrative that builds to an epic climax, but there's plenty of flexibility built in to give characters freedom of action. It involves an arduous journey deep into enemy territory and darn chilly to boot. Structured as a five-day mission, each day has several scenes that provide the main meat of the story. It all begins with the party being dropped off from a British submarine somewhere off the Norwegian coast and having to make their way ashore in canoes. Here they will meet the Norwegian resistance and make their way overland to the scene of the action. Well, that's the idea, but there are some perils along the route...
As the adventure unfolds there are plenty of opportunities for combat, an encounter with a bear, and a chance to learn quite a lot of Norse mythology - some real and some most convincingly invented for this story! There's a lot going on and no time to get bored although there is plenty to get scared about.
The adventure itself is followed by pre-generated characters, a collection of allies and adversaries (including a new Mythos monster) and a rules section that covers such essentials as Nordic skiing, canoeing and arctic survival, as well as new spells and equipment. This is followed by a handout - a multi-page work entitled Diary of a Madman which the characters ought to find along the way and which might provide them with some clues as to what is going on. It repays careful study.
It's an atmospheric and exciting adventure based on a novella written by the adventure author and also available from Modiphius. Indeed if you are running this adventure, the novella will give you added atmosphere and descriptive material.
