Long before the attacks by the Carja known as the Red Raids, Jom was cast out for manslaughter. He had been lazy, refusing to fulfill his responsibilities as a Brave. He had also been a troublemaker, frequently picking fights with other Braves. However, one such fight grew very violent, ending when Jom fatally struck the Brave, resulting in his being cast out.
His time as an outcast impacted his attitude and he became very regretful of his past behavior, eventually accepting his punishment as justified.
While on his own he encountered other outcasts, many of whom had been cast out for as long as he had been, or even longer. Although Nora law forbids outcasts from speaking to each other, Jom realized that his survival was very unlikely if he remained on his own. He therefore convinced the outcasts he met to speak to each other and join together in a group with him. While they were still exposed to threats such as bandits and machines, their community allowed them a somewhat better chance of survival.
After spending years as an outcast, Jom and his peers watched as the Nora Brave Aloy cleared out a bandit camp near the Old Ones ruin known as Devil's Thirst, killing all the bandits in the camp. Tired of living without protection and refuge, Jom asked Aloy on behalf of the group if they could make the place their home, as it was fortified and defensible. Aloy agreed, earning Jom's gratitude.
