While at Hunter's Gathering, the Nora Brave Aloy overheard Lubavad, a Carja trader, as he was attempting to persuade the Banuk hunter Opitak to find a convoy he had sent out, but the Banuk refused to go without being paid up-front.
When Aloy asked him about the situation, he relayed to her that he had sent out a convoy carrying valuable merchandise, on a dangerous route to trade with the Banuk. The danger was due to attacks from machines, and the convoy had left the ammunition for their weapons behind. Aloy offered to take the ammunition to the caravan. Lubavad gratefully agreed, though he warned her that there were rumors of a Machine prowling the area that had not been previously encountered in the region, and was far more dangerous than the Scrappers and Longlegs that were known to prowl the trail.
