Neat, does this cult have any deities, or is it more philosophical than anything? We could probably throw Gaia, the Wicca pantheon, and esoteric spiritism in there, with Karl Marx and long-dead sjw pioneers as saints. We could claim that new, negative spirits seek to take over the world, and suppress nature under their fascist boot, and that the positive spirits and negative spirits have been waging an invisible war in the shadows since civilization began to abandon the wisdom of the ancestors.
To tie into their Nazi hate and give the cult evil trickster god to rally against, we could claim the Weimar republic was on the verge of transcending into a vibrant and beautiful liberal utopia, but that out of hate, the negative spirits gave an evil patriarch, (Adolf Hitler, the Supreme Patriarch) the power to brainwash the German people to destroy the enlightened civilization they had created, and attempt to exterminate and enslave the First Peoples.
Ever since the Supreme Patriarch was defeated only through the bravery of the positive spirits and the courage of their mortal followers, his spirit, the Black Wolf, or, Umbral Lupine, has been corrupting the love in people's hearts into hate, which is why the negative spirit's next mortal servant, the Orange Deciever, managed to conquer the world's greatest nation without firing a shot. Only through peace, hope, and the spread of Sapienta's noble message, can love prevail!
