Not that she imagined the project, but rather that it's fanfic about a TV series that never really existed.
"Elizabeth Bear has been urging her published writer friends to try writing fan fiction, because it's a great way to remind ourselves that, ultimately, writing is fun, that that's why we're doing it," Bull said in an interview. "I wrote a Criminal Minds novella [based on the CBS TV series] and had a great time. But it made me realize that what I really wanted was to write fan fiction about a show that was a little like Criminal Minds, a little like The X-Files, a little like Man From U.N.C.L.E. and Mission: Impossible and Millennium and various other shows I loved--plus a few comics series."
Bull decided to create the show herself--with the help of some of her writer friends--but as a Web site rather than a TV series or a novel. She co-wrote the "series" bible with her husband, author Will Shetterly, and then started recruiting other authors to take part in the project. First, she brought Elizabeth Bear on board, then Sarah Monette, and she selected some other support personnel to help with the Web site and art direction.
