Guys I had a thought of an original universe
so basically all these people have been tossed into a strange, new decaying world that will eventually disintegrate into nothing and they will all die when that happens (assuming they don’t kill each other before that), and these people try to survive as long as possible with their limited time and resources, factions are made, bonds are created and broken, and as the world dies the people get more desperate and start doing drastic things, for example when the food runs out and they have no method of getting more they turn to cannibalism, opting to eat the weak ones first so the others can survive, they all lose their sanity at some point, as being alone in a barren, desolate wasteland with nothing to survive with will do to you, and they the last of them dies and the world pretty much ends so yeah that was my thought
