General Systems Bus

The General Systems Bus is a subregion of Five Pebbles. In this area, strange symbols (similar to karma symbols, and including some) move around in sync with each other, as if they were written on a rigid, transparent material moving independently to the game world. Roughly at the center of the biggest room in the General Systems Bus is a square room about the size of the screen that contains the region's Iterator, the namesake Five Pebbles. When the player comes into this room, Five Pebbles will give the player the highest level of karma (an X symbol), and the mark of communication. This mark of communication is required to talk to Big Sister Moon, as well as the Echoes.

Trivia

 * Passive music can be heard in this subregion which increases in volume until reaching Five Pebbles' puppet. This music is meant to sound like processing noises. These noises can be heard in the shelter next to the region gate that leads to the Wall.
