I thought we don’t do this here, for such things there is WIAB
In my childhood, I read a fantasy novel (kill me if I remember the title and author), something like an urban fantasy, where aliens were stealing from people their intangible life essence, which, most likely, can be called a soul. Technically, their human agents set up a network of relaxation or healing parlors where people were put to sleep using an alien technology. In this artificial dream, people would find themselves in their ideal imaginary world and live happily there, while their souls were slowly sucked out by an alien device and they soon died eventually of seemingly natural causes. Everything was fine, until one side effect began to appear - under certain conditions, elements of some people dreams began to seep into reality. if I remember correctly, the novel begins with MC watching the news that some unknown monster rats attacked a passenger on the subway. And a long investigation led him to the damn aliens.
That was the preamble
My point is, aren't you afraid that this tabletop bullshit will seep into the main story and consume it completely, like in that novel I just mentioned? And nothing will remain but the harem and the NTR. I'm telling you, f'ckn aliens can't be trusted!
