Oseram's Rise

Forged in fire and stone, they shape the world from the earth's bones.

The Oseram are one of the major human tribes inhabiting the post-apocalyptic world of Horizon Zero Dawn. Known for their mastery of metalworking and mining, they emerged from the survivors of the Collapse who settled near Old World industrial sites. Their history represents a unique adaptation to the new era, prioritizing resource extraction and craftsmanship over agriculture or solar worship.

Lore & Background

Following the devastation of the Faro Plague, humanity fractured into isolated groups. The ancestors of the Oseram found sanctuary in the rugged highlands where ancient mining infrastructure remained intact. Unlike other tribes that worshipped the sun or revered nature spirits, the Oseram developed a culture centered on the practical utility of metal and stone. They view the Old World ruins not merely as sacred sites to be avoided, but as repositories of raw materials necessary for survival. Their society is structured around guilds of artisans and miners who work tirelessly to extract resources from dangerous territories often patrolled by machines. This relentless industry allowed them to craft superior armor and weaponry compared to neighboring tribes. While they maintain a stoic demeanor, their history includes periods of conflict over territory and trade rights, particularly with the Carja Empire. Their resilience ensures that even in an age dominated by robotic beasts, human ingenuity continues to thrive through the hammer and the furnace.

In Their Own Story

The wind howled through the canyon, carrying the scent of sulfur and wet rock. Kael adjusted his leather straps, checking the charge on his spear before descending into the dark throat of the mine. Below, the hum of a Strider echoed against the cavern walls—a reminder that the earth was no longer silent. He signaled to his team, their torches casting long shadows against veins of copper exposed by Old World drills. They moved with practiced silence, knowing that greed could wake the machines sleeping in the dark. One spark could mean death, but without this metal, their people would freeze before winter.

Reader's Guide

Following the Great Collapse, survivors scattered across the scarred landscape. Among them were those who sought refuge in the rugged mountain ranges and deep valleys where Old World mining operations once thrived. These groups eventually coalesced into what became known as the Oseram tribe. Unlike the Nora or Carja, their culture centered heavily on the extraction of metal and stone from the earth. They viewed the remnants of the old world not just as relics, but as resources to be utilized for survival and strength. Over centuries, they established fortified settlements near these deposits, creating a society built on craftsmanship and physical endurance. As machines roamed the wilds, the Oseram adapted their mining techniques to avoid triggering automated defenses while scavenging useful materials. Their reputation grew as skilled metalworkers who could forge weapons superior to those of neighboring tribes. This industrial capability allowed them to maintain independence from larger powers like the Carja Empire for much of the early centuries. However, tensions often arose over resource rights and territory, leading to skirmishes that defined their borders. By the time Aloy arrives in the world, the Oseram stand as a formidable faction.
