Their town is called Rio Villa and is in the south-western part of the planet. They also run a power plant in the Kahve Ruins in the north of the planet.

The robots center of the power plant is called the Emerald Core.

You first steal your Neumann spaceship from the robots when escape from Erd. However, there isn't a Mystic Mouse to control where you go, forcing you to crash land on Cassia .
The robots have built gates that only they can control so as to prevent other peoples from moving freely around the planet. They are of the Earth Starsign when you battle them. Rio Villa is overrun by the Space Police when they are attempting to capture the player with Magnus Muzzleflash.
