In the real world, it is a quantum-stacked memory symbol that secretly governs everything in the Mechanical Forest, constantly accelerating the growth and reaction of metal life.
This symbol is like an invisible net that covers the entire planet, mostly staying dormant and objectively existing, just like the basic physical rules determined by the stars in each planetary system.
As long as someone triggers the defense system, or enters the range of the ecosystem, and is perceived by the omnipresent mechanical creatures within, this net will awaken instantly like human consciousness.
The consciousness flow carried by this stacked memory symbol can traverse vast distances in an instant, as if the Eye of Cthulhu is watching the intruder, and reading their memories.
