The Universal Machine, called UniMac for short, was the embodiment of all tools created throughout human history. It was capable of reaching through time perceiving, recording, and copying any machine ever built by humans. It was one of the Secret Architects that built the City of the Saved.
The Universal Machine was nearly manifested on Earth in the 21st century, (PROSE: Of the City of the Saved...) but intervention of War-time powers ruined the attempt. (PROSE: This Town Will Never Let Us Go) It was finally successfully manifested by Mesh Cos more than 300 billion years later. (PROSE: Of the City of the Saved...)
