There are a few in this jam (including my own, although I don't think I'll go this route) that I think could be used as a free download to tease a larger zine-type module. This is maybe the best example of that because of the way it sits somewhere in between being just a setting and being a scenario. People could read the pamphlet and then decide whether they want to just build their own scenario around the cataclysm you've laid out for them, or buy the full thing where you've got say a three-Scenario arc of which the cataclysm is just the final one.
