Thule Society

The signet ring of the Thule Society as worn by Eckhart

The Thule Society is a group of necromancers with plans of world domination. They originated in Europe and sponsored the NAZI parties in its early days. The Judah Initiative was formed to fight them.

In Vitsyebsk, Belarus following the NAZI occupation in World War II, the Thule Society established a camp where they carried out terrible magical experiments on the Jewish people in attempts to reanimate the dead. Commander Eckhart devises the experiments and records the results, which eventually lead to him being able to revive dead NAZIs, in a red ledger. The reanimated soldiers could be killed with a head shot but will come back to life unless it is burned within twelve hours.

The Judah Initiative raise a Golem to destroy the camp, but Eckhart uses magic and escapes but the red ledger is left behind.

8.13 Everybody Hates Hitler

Torvald, a member of the Thule Society, follows Rabbi Bass, eventually causes him to combust after he locates the red ledger which both the Judah Initiative and the Thule Society have been seeking for decades.

When Sam, Dean and the Rabbi's grandson track down the red ledger, Torvald tries to take it and shoots magic poison dart into Sam and Aaron until the Golem kills him and the spell is broken. Sam and Dean burn his body.

Eckhart and his men track down Aaron and the Winchesters and break in to steal the ledger. When Aaron causes a distraction, Sam and Dean are able to shoot two of them and Eckhart, but one escapes.

Aaron takes possession of the Golem and vows to continue the work of his grandfather and the Judah Initiative.
