File:Tetro community.jpg

This image was collaboratively created by several artists at the Unity Council (Earth-year 1921) to represent Tetro's global community. The three icons superimposed over the planet represent three of the world's types of organism: magnetates, eukaryotes, and pyronates. The lack of a photonate in the image has been a major political controversy from the time the image was released until the present. No resolution of the issue is foreseeable in the near future.
