Why not, @killertofu? When you create fiction, you can make up anything you want.
I created a web page that gives a detailed history of a woman from the Middle Ages who left an interesting legacy of occult practices and lore, passed down through her daughters. The page is written in a textbook style, very factual and analytical in tone, with footnotes citing several authorities, including a couple of works translated from another language, giving full bibliographic references. It also contains illustrations, including one from a medieval manuscript.
It is all my invention: the woman, her biography, her genealogy, her practices, the lore, the authorities, their names, the titles of their books in English and French, the publishers of those books, and the illustrations. All completely made up, and sounding as genuine as I could possibly make it. I worked very hard to make everything sound absolutely real, and I did a lot of research to sustain authenticity. I would do the same thing if I were writing a novel: tell the made-up story as if it were true. Wouldn’t you?
Have you ever looked for a quotation to make a point and couldn’t find one to suit your purpose? I have, so I invented an author and a fictitious work from which I posted quotations. The book does not exist; just the quotations. Then when I couldn’t find the quote I needed, I could just write one, attribute it to her and post it on that page, and then cite it. People always think something means more if you quote somebody.
A couple of years later I found my fake author and one of my made-up quotations quoted in a discussion on a serious philosophical website! I laughed so hard and long that my husband thought he was going to have to call 911.
