Mason serves as the central hub for droid activity. It also houses most of the droid population, oddly enough. Most droids make their commute to other Arcs but live on Mason, so as to keep better track of the population.

Sacret is the factory-based Arc, having very many droid- and human-operated factories here. The Arc is in poor condition, and many crime lords make their living here.

Tiskal is the docking Arc for droids. As with Sacret, crime lords dwell in these areas, but the Arc is very well kept, as it is constantly getting traffic from all around the world.

Like the humans, droids also have smaller satallite Arcs. However, these are usually added onto larger arcs, such as Tiskal and Mason, when new buildings or larger populations give need to larger Arcs.
