1908. Siberia. Tunguska. An explosion rips through the frigid skies over the vast Russian tundra, destroying the uninhabited forest for miles. A strange machine from another world has arrived that will alter the course of human events forever. For a disgraced Czarist colonel in a remote backwater village, it promises his return from exile. For an upstart Bolshevik from Georgia, it promises world domination. To reach out and grasp that power will take an ambition forged in steel.
