Unholy Raptures of the Deep
Adventure seed
Via here. See here for background.
So, five million years or so ago something was operating off what is now the island of Zakynthos, off the coast of what is now Greece. We – ‘we’ being ‘whatever shadow government agency it is that handles this stuff in your world,’ of course – aren’t sure what that something was, but it definitely involved at least two kinds of aliens. The first type apparently had endoskeletons and bodily functions similar to those of terrestrial life (while still being highly bizarre); the second seemed to be more, well, protoplasmic. Fans of HP Lovecraft who are thinking ‘Elder Thing survivalists served by barely-tamed shoggoths’ aren’t necessarily right to think that, but the evidence doesn’t really contradict that theory, so no worries there.
No, the worries were over the aftermath of the discovery of the site in 2014. The problem is, of course, that whatever it was that’s down there is apparently still there, and it’s aggressive. There were no reported deaths, but at least a half dozen reported attacks by ‘water that moved through the water,’ as at least one person frantically reported. This one got expedited by usual Shadow Government standards; which makes sense, given that Greece has been in the grips of some serious social upheaval lately – and that never mixes well with anything eldritch. So they came up with the ‘natural phenomenon’ explanation, coupled it with one of the more ingenious uses of ‘there’s a gas leak’ excuses to keep people away (Watch out for those Ancient Methane Beds!), and told everybody who was attacked that they were undergoing the Raptures of the Deep. Pretty standard stuff, really.
Only… the half dozen people who had been actually attacked? Every single one of them has since dropped off the grid. And they timed it to take advantage of various agencies’ reporting periods; June 1st was the first time that anybody could start putting the pieces together. Guess that it’s time to investigate that, huh?
