However, I'm not certain, as the whole religion-founded-by-a-science-fiction-author thing complicates it immensely.
A quick scan of the Wikipedia article indicates that L Ron Hubbard intended the story in question to be a dramatized account of events that are pivotal to the Scientologists' belief system.
Additionally, the story itself is unpublished, and the copies and summaries circulating around the Internet are "unofficial".
This makes it much harder to determine if the question is about the actual science fiction work (if, indeed, it is categorized as sci-fi instead of religion), or about the religious beliefs the screenplay is intended to dramatize.
Are L Ron Hubbard materials that are intended to depict events that are part of Scientology belief on-topic, or off-topic per our policies on religious texts? Presumably the L Ron Hubbard works unrelated to Scientology beliefs (such as Battlefield Earth) are not an issue.
Even if works by L Ron Hubbard that discuss the beliefs of Scientology are on topic, is this particular question on topic? As I mentioned before, it could be argued that the question is really about Scientology beliefs, rather than a specific work, since the work referenced is unpublished, unofficial, and not directly quoted.
