The Background (Part 4)
From the misery and destruction of WWI, the Thule Society began its work, recruiting magic users, and creatures from other worlds forced to hide themselves by Entente governments to create an army that would take over the world. But they chose to act discreetly and not openly, believing that maintaining the masquerade fro the time being would work to their advantage.
To their surprise and delight, fascist ideologies similar to their own took power in formerly Central Power nations of Germany and Italy. The Thule leadership took the opportunity to present themselves to the Third Reich as their own equivalent of the Entente's Institutes. Offering them their expertise in magic in exchange for a place at the top of the hierarchy once the world belongs to the Reich. WWII was fought even more so with magic, with Institute and Thule agents clashing covertly all over Europe without much of mankind's knowledge.
