A Ripped From the History Books Scenario Hook for Trail of Cthulhu
The exact extent to which the 1938-39 Tibet expedition led by explorer Ernst Schafer served the Nazi agenda remains a matter of controversy. After the war, Schafer claimed to have come by his posting as an SS Hauptstrumfuhrer unwillingly. Also unclear is how successfully he derailed Himmler’s goal for the trip—to have Ahnenerbe pseudoscientists measure Tibetan skulls in an attempt to prove that Siddhattha Gotama, the historical Buddha, had been an Aryan in good standing.
Perhaps the greatest mystery is what Himmler thought he stood to gain by proving this, given the incompatibility of Nazi ideology and Buddhist thought.
If we fictionalize it a little, though, we get a Trail of Cthulhu scenario of high altitude high adventure.
When a politically fervid fellow inquirer into the mythos conspiracy goes missing in Tibet, the investigators follow his trail. They discover his plan to infect Himmler’s minions with contagious madness, by leading the Ahnenerbe to the Plateau of Leng. Do they help him destroy Nazi scum—or see the vast potential for backfire, and work to thwart him?
