Interesting Apocalypses

Broadcasts of patterned radio noise being blared into the universe are mistaken for Space Whale mating calls causing hordes of sexually frustrated whales to "beach" themselves towards the source of the signal like moths flying into a lightbulb but with more apocalyptic dinosaur-killer asteroid-ishness. Incidentally, this is the explanation behind the fermi paradox as any planetbound species which starts using radio inevitably gets themselves killed by kamikaze cetaceans.

In one of my abortive games, an entire continent is abandoned because the mad Empress of the Ancient Magical Empire decided that the world was too ugly. She cast a spell that essentially transformed the entire continent into a perfect garden, overgrowing everything with massive plants and flowers. People unfortunate enough to be unable to be hit by the magic, since it spread in waves rather than being all at once, became plant monsters made of tightly wound vines living in primitive tribalism. Almost everyone fled the continent if possible, but now people are trying to penetrate back in to recover the magical powers that were lost when the gigantic, impossible cities became overgrown. At the center of the growth the Empress still lives, tending to her garden and pulling any weeds that invade it.

And then fucking Annihilation came out and used a lot of the imagery I was going for, so now people will think I'm ripping it off.

Interesting, though it strikes me as way too much projection. Great fictional premise though.

Is this off a generator? And if so can you link to it?

i ran a magical apocalypse setting where a group of wizard created a spell that killed all non magical beings on the planet
basically the world turned into world wide Ravnica

The main argument against it being dangerous to broadcast obvious intelligent signals into space is that anyone else out there who destroys us will, by doing that, indicate not only where they are but that they are specifically threatening to other intelligences, at which point every other civilisation that saw our signals and waited for someone else to shoot first turns their guns on that civilisation, destroys them, and then proceeds to peacefully coexist with all the other civilisations who they know could destroy each other but can also decide not to.

So we're fine until that one stupid actor falls for the obvious bait we represent.
