Welcome, investigators, to our tale of cosmic horror. The year is 2137, and humanity has expanded its reach into the far corners of our galaxy. Our story begins on Proxima Centauri b, a once-thriving human colony that has been condemned due to its unstable orbit. You see, Proxima Centauri b has been caught in the gravitational pull of Sagittarius A*, the supermassive black hole at the center of our Milky Way. Scientists calculate that the planet has roughly seven Earth days before it crosses the event horizon. All colonists were evacuated months ago... or so everyone thought. Your team of specialists has been hastily assembled and sent to retrieve valuable research data from the Hawthorne Research Station, but upon arrival, you've discovered disturbing signs that not everyone left the doomed world. The radiation levels are rising, and the very fabric of reality seems to be stretching thin as gravitational forces warp space-time around you.
