As expected, it focuses Filip and it takes place post-Gate closure. He was working in the transport union and was on a contracted project when the gates shut down, so now he is stranded. The system he is in doesnt have much, it was mostly a mining and science concern. They have no ship or shuttles, or even any powered transport. The only other city on the planet is over 7KM away and they lost communication. The town he is at only had 400 people or so and the migration of some sauropod sized aliens threatens their settlement - they aren't aggressive, but they dont give a fuck and basically have been trashing the town because it happens to be in the way - which is a big deal because there is no resupply and they aren't really self-sufficient yet and on borrowed time.
By cosmic coincidence, Anna's daughter happens to lead the settlement. The settlement has a vote: move the town so the aliens arent an issue, or make defenses. Some tough dude in the town wants to make defenses and Filip sees shades of his father in the guy. When the guy basically overrides the vote, Filip decides to take matters into his own hands and kills the dude, because if this settlement potentially is the start of a new civilization on this planet, he doesn't want another Marco Inaros figure. He gets exiled from the town for no shorter than 5 years (he estimates the town can maybe survive 6-7 years unless they figure out solutions for power generation after they run out of fuel) and they basically give him some minimal stuff to ensure he at least has a chance of survival. Filip decides that he will at least try to make his way to the other settlement to figure out what happened and it ends there.
Doesn't really resolve anything and paints a pretty bleak picture of the long term survival chances of the settlement
