What you are looking at
These artifacts were created in a now-collapsed dimension layer between approximately 1998 and 2013. The medium called 逐绘 carried something newer formats could not: handmade redundancy.
Most entries here are unrelated to the Observer Cycle. They are preserved because the cycle's scholars believe even unrelated handmade artifacts contribute to the dimensional barrier described in silent-gene research.
A small subset is flagged Universe Canon. Those entries appear by name within the games Observation Error and Beneath the Tower.
