Fortunately it's not our world as we know it. But it's derived from our darkest.
The town will be destroyed by another ugly people. Wait, it is filled with those ugly folk, like the worse of split personalities transformed into. No, it's an epidemic that slowly mutates decent humans into worse. But - what? The town upper class speak ugly?! Who's what now?
Next, it's a party of big shots with masks. Not a red death, silly, but involving put-on flesh in the end. And a helpless one for which the most powerful have to attend, each alone with the worst of no usual formidable defences. So soon is still certain, as they finally get ultimately replaced. And the utter defiance of the worst of these entrepreneurs: you know, futile.
Then, shift to another world site: seasoned gladiators don't fall in willing disgrace. After all, like Valhalla, they're magically resurrected whole, to pointless gloat-able carnage once more. But the game-indulgers didn't figure out the glorious sacrifice of suicides, of their favourite pet deaths, assumed recyclable. Till now, since the selective AI overlord only revives those worthy of being recurringly exploited thus. The system crashes.
