The search for the Queen of Witches finally ends when the Dancing Hut travels to Baba Yaga's homeland of Russia on the planet Earth. The year is 1918, and the First World War rages throughout Europe. The heroes find themselves in the wilds of Siberia, where they must face Russian soldiers armed with 20th-century technology to infiltrate an ancient monastery and rescue Baba Yaga from her estranged son, Grigori Rasputin. Can the heroes kill the "Mad Monk," who has already cheated death once before, and free Baba Yaga, or will they too fall before the horrors of modern war? "Rasputin Must Die!" is a Pathfinder RPG adventure for 13th-level characters. This volume continues the "Reign of Winter" Adventure Path, and includes details on the soul-harvesting worship of the daemonic Horseman of War, new rules for World War I-era weapons and equipment, and a new occult oracle mystery based on 20th century mysticism! Several new monsters in the Pathfinder Bestiary and author Kevin Andrew Murphy's new Pathfinder Journal novella rounds out this exciting volume of the Pathfinder Adventure Path!
