How to Complete the Line in the Sand Quest
Like most quests, the Line in the Sand quest triggers after reaching a certain area of the Buried City map. Once the quest is triggered, you will get several quest objectives. With each objective, you need to explore the map to uncover how to complete them. Let’s take a look at each step and how to do them one by one.
Find Out Why The Train Never Reached Marano Station

To start the quest, head south directly from Marano Station POI, just between Piazza Roma and the Warehouse. You will find these locations on the western side of the map. Check out the derailed train half buried in the sand to get the next quest objective. During my time with this quest, I couldn’t get the next objective to appear until I stood on the train itself.
Find Out Who Orchestrated the Robbery

From your previous location, travel a bit east towards Piazza Roma. Look around for a lone broken tower jutting out from the sand. Enter the tower through the large open window and check around to find a box you can interact with in the corner. I had to look around the floor for a while since the box was tiny, but hovering my character over every inch of the floor helped me identify it. After interacting with the box, you will receive the Marano Market Business Card.
Find Out Where the Thruster Valves Were Stashed

You now need to make your way to the New District region in the eastern section of the map and travel all the way north towards Market Ruins. Once you stand in front of the building marked on the map above, you will be tasked with checking out the merchant apartment’s basement.
Search the Basement

From the ruins, travel far east towards the outskirts of the map. Enter the building through the front door and go through the open doorway to find a zipline to take you down to the building’s lower floor. After landing, go through the doorway and interact with the boxes on your immediate right. You will get the notification to take a photo. Do just that, which will end the quest.
