The Uplifters

Lore & Background

According to established history, the Uplifters arrived eons before the current timeline. They engineered specific planetary environments and introduced humanity as subjects of a grand sociological experiment. Their intent was to observe how isolated human groups would develop without external interference, creating a galaxy-wide network of RimWorlds. They left behind vast infrastructure, including automated defense systems that now roam as Mechanoids. These machines continue their programming long after their creators departed, posing threats to modern colonists who stumble upon them. The Uplifters also manipulated human genetics, resulting in the diverse phenotypes and abilities seen among current populations. Despite their absence, their influence is omnipresent. Every piece of Ancient Tech found in a ruin is a remnant of their civilization. They serve as the ultimate mystery of the setting; players can uncover clues about them through exploration, but they will never meet a living member.

In Their Own Story

The wind howled across the barren plateau, carrying dust that had settled for centuries. Kael brushed the grime from the monolith, revealing smooth, obsidian-like surfaces that hummed with a low vibration. It was not stone, nor metal known to any modern smith. As his hand hovered over the glowing glyphs, the air prickled with static energy. This was not a ruin of men; it was a testament to those who came before. The Uplifters had walked here once, setting the stage for humanity's struggle long ago. Kael felt the weight of their gaze from beyond time, watching him decide whether to activate the device or leave it buried in the dark.

Reader's Guide

The Uplifters serve as the foundational mythos of the RimWorld universe, explaining why isolated colonies exist on distant planets. According to established lore, this ancient civilization selected specific worlds to act as controlled environments for human development. They seeded these locations with humanity and advanced technology before vanishing from the galaxy entirely. For players, understanding the Uplifters provides context for the Ancient Tech found in ruins and the mysterious nature of Mechanoids. Their absence drives much of the narrative tension; colonists must survive without their guidance while uncovering dangerous artifacts left behind. Some theories suggest the mechanized enemies are automated remnants of this lost race, continuing to patrol the worlds long after their masters departed. Ultimately, the Uplifters represent the unreachable past. They set the stage for human struggle, offering tools that can elevate society or destroy it. Their legacy is written in every piece of alien architecture and gene-modified organism found on the surface.
