Now you've reached Serrano, and dug deeper into the rabbit hole.
Serrano was a Chilean Esoteric Hitlerist that was inspired by Savitri Devi's works, and he wrote multiple books on the subject like the one above, along with a few others. He spent the rest of his life researching occultism in NS and Esoteric Hitlerism.
