Steven W post is the only thing I found as well. I don’t have anything other then that yet
The cover of the manifesto supposedly has a black sun diagram.
The black sun (German: Schwarze Sonne) is a symbol employed in a post-Third Reich context by neo-Nazis and some occult subcultures, such as Satanism. The symbol first occurs as a design element in a castle remodeled and expanded under Heinrich Himmler during the Nazi era. The symbol’s design consists of twelve radial mirrored sig runes, symbols employed as a logo by the Schutzstaffel. All subsequent forms extend from this mosaic. Whether the symbol had a name or held any particular significance among the SS remains unknown. Its association with the occult concept of the “black sun” (and therefore also its name) developed from the influence of a popular German novel first published in 1991.
