Static Fiction

Most fiction that people read is in the form of stories. It would even seem that the story is the prototype for fiction. This is quite obvious, in many ways. However, there are other basic story prototypes, and they don't necessarily exclude one another: the setting, which tells us what to expect of any story within it, the archetype, which is a basic set of patterns a story can be expected to follow; more recently, tvtropes (and I won't do you the disservice of linking there) has categorized and documented - in excessive and sometimes counterproductive detail - archetypes and common variations of them.

Both of those are arguably static fiction. Oh, certainly details in the setting can change - the federation and the klingon form an alliance, the elves depart for wherever, SPECTRE dissolves and is never heard of again, ... but all these are still, in a way, static things about the setting: stories set after stardate so-and-so, in the fourth era, after 197x, ... within a  setting use the updated assumption.

However, more genuinely static forms of fiction do exist. I recall running into a novel that was written and structured like an encyclopedia. I recently tried finding it again, and I am pretty sure it was Milorad Pavic's Dictionary of the Khazars. I intend to read it soon, and once I have done so, I will post a review here, as I think the form he picked for it might be of some interest for conworlders and conlangers alike.

Nevertheless, a conlang, a map of a world that does not exist, an actual artifact emulating a non-existent culture, or even a non-narrative "paper" emulating the (academic) style of historians, sociologists, theologians, physicists, chemists, astronomers, (even magicians, alchemists and astrologists) of a culture that does not exist could be rather fascinating. The artifact would be intriguing - it is both an object of fiction and a work of art.

For me, language is the most interesting kind of speculative non-narrative fiction, but even then, it is not the only kind that could be of interest.
