Little more background info on Part Four

and no I'm not just doing this to increase my post count.
The Caranck Border is the border at the edge of a solar system. Beyond the Border there is nothing of interest save for a few comets and the odd Oort cloud. It represents the edge of the system in SEIV. Ships don't normally go beyond the Caranck border. Tamarillho's impulse to say she didn't care about it meant that she was willing to go into really empty space far out of reach of any help just to try and shake off the chasing

Yes, I am naming all my freighters and other transports after British cities

The reason the Vulture (or NKCS Star Asteroid as its official name goes) doesn't carry a name like this is because salvage craft aren't considered real cargo transports, since they have to pick up debris before transporting it.
When Terlan (the nav officer) mentioned "C-Devonshire" he meant C-Alpha 5 Devonshire. C-Alpha 5 Devonshire is the central command station for the Devonshire system. It relays all orders and almost all comms traffic in the entire system, and coordinates system defenses and economy. All Kytheran systems are commanded by a C-[class] [subclass] [system name] station. Alpha is the class. It is a general-purpose "inner rim" command station, designed to coordinate a system close to the core of the Commonwealth. Beta is a more military station, while Gamma is a station with a focus on economic coordination. There are more types, but most are simply small variations - usually in size - on the ones mentioned here. 5 means it is of subclass 5 - the highest level. When a station is first constructed, it is level 1. As its comman duties and capabilities increase, and more additional sections get constructed, it raises in level. The maximum level is always 5. Devonshire speaks for itself; it is in the Devonshire system.
