A while ago I read a story online about a planet which was almost tidally locked but not quite. I don’t know if it was a forgotten colony world of humans or an alien world but there was a first contact situation of someone from that world telling their story. It was written as an interview I think.
The people lived on the thin strip of land which was habitable between the area which was in direct sunlight and too hot to live in, and the area which was facing away from the light and covered in glaciers. Because the planet was rotating slowly, the people were always migrating. They might get a few years in one place before it became too hot to grow crops and they had to move on. There were people who would go ahead and prepare land for farms in ice, which was a dangerous job. And there were people who would scavenge for what had been left behind when people had to move on, which was often looked down upon as a job.
I don’t know if it was originally on tumblr, reddit, or somewhere else but I really want to find it again. Thanks
