Tarn Region - Cybertron If a new Cybertronian society were to emerge without the baggage of the Autobots and Decepticons, it would surely come from Tarn Region. With the exception of Tarn itself, several major neutral city-states reside here. From the dour and depressing spires of Kalis to the technological wonders of Tyrest, to Vos with its sharp class divide between those who live up high and those who live below, Tarn Region has something to offer everyone. Many neutral inhabitants choose this as their home, and so the roadways are often crowded and lively with merchants and transports. Only Tarn itself stands alone, still under strong Autobot military control. This gives the Autobots nominal control over the area.
