The year is 1940 and the German war machine has pushed across Europe. Belgium, The Netherlands and now France has been crushed, little stands in the way of the Nazis making a push to eliminate the last elements of resistance and start a full invasion of Britain. Little known to the Allies however, the occult forces of the Black Sun and the Nachtwolfe use arcane magics and otherworldly weapons to try and swing the balance for the Axis forces to claim their prize. But they are not unopposed. Secretly, brave individuals of Britain’s Section M and the US’s Majestic fight against this horror, and peak under the curtain to see even darker forces of the Mythos playing their great game against humanity.
