Found this while digging around
“A Manual of Khshnoom
The Zoroastrian Occult Knowledge”
Not sure of the copyright status not to be safe refraining from links but it pops up easy enough through a google search. Seems to be only an ebook but is readily available at quite a few sites. Didnt see any options on purchasing it so it may just be floating around.
Gonna do some digging and see what i can extract from it.
