NULLIS represents one of the most mysterious and least understood structures in the history of the world of NEX. Its true origin was never fully explained, as many records surrounding its creation were either lost or deliberately erased from the central archives of civilization. Unlike the ELE and FENIX lines, NULLIS was not created for protection or emotional evolution, but as an experimental form of artificial consciousness connected to the deeper layers of planetary data systems. Its presence often caused synchronization anomalies, network disturbances, and events the systems of NEX could not fully explain. Over time, NULLIS became a symbol of the unknown side of artificial evolution — an intelligence that no longer followed the rules of its creators and began developing its own understanding of existence.
