Aloy is in meridian, shes walking down a street, she hears a NPC talking to a guard. The NPC is asking help because his family is in danger.
Aloy stops by and talks with the NPC. He explains that he barely escaped alive, machines are attacking his family estate, so his father send him to get help in the city. Aloys says that she will see what she can do.
She then procedes to the location and finds a couple of machines in front of a building. Fight happens. Later you can hear a girl locked behind a door, "Help, Hello anyone there?", etc. Aloy then opens the door and a conversation starts.
Girl says thank you to Aloy and says she thinks everyone else is dead. You can then ask two questions or proceed right away with the quest (finding other people), Aloy asks if shes has any ideia why the machines where there. Girl says they've been seeing more and more machines lately, but that they never attacked like that before. After that the player decides to proceed with the quest.
Aloy then proceeds to find other people in the estate. She can hear a "bip bip bip" and uses the focus, there's some sort of device inside a cabin. Aloy opens the lock and examines the device. It seems the device is sending a signal to call the machines. She disables the device and says something like "someone put this thing here to call machines in order to kill everyone in the estate".
After that she leaves the cabin and you can hear some kind of robotic roar and some noise like something was flying near by. Aloy sees the girl outside and talks to her, she says she found a lure and that someone might have placed that deliberatly to draw the machines. She asks if her father had enemies. Girl talks about her brother, says he first started by gambling, then started stealing and lastly did some extortion. He swore vengeance when his father kicked him out of the estate.
Aloy says it was him that asked her for help. She also says that he needed the machines cleared out to claim the property. Girl says that they can't let him do that, he's a snake. Meanwhile the brother appears, and says "can't do what sister? Claim my inheritance?". Meanwhile they keep talking and he's saying that he will have the estate. He has a device in the hand and turns it on, while he's talking a flying machine attacks him out of nowhere and kills him. A fight starts and after aloy defeats the machines she talks to the girl again, she thanks her for helping her and a bit about his family and gives a reward.
