In fact I randomly determined it was Talin. You picked it up on your now fully functioning comms network. Someone is on duty at all times (with a lot of you these days, you can spread those shifts quite well) listening to various Galactic transmissions so you can keep up with what is going on out there.
Ok, as ever, I don't have a name for you, but I will soon.
The transmission is from the Treganna Void. The Void is one of the notable power blocs that exists outside of the Republic. Its historical origins lay in a bunch of pirate clans that did extremely well for themselves and eventually settled down as rulers of a bunch of planets in a general area, and these pirates-turned-overlords eventually ended up running their own small Empire- though only 'small' in Galactic terms; it still covers many star systems.
The given name of 'Void' is actually just down to perspective. From within the Republic there appears to be absolutely nothing there. This is because iof a vast nebula of tiny abrasive particles that absorbs all light that passes through it. To those observing this area of space it looked like a void, a black hole in the cosmos. Whereas in fact the Void is no more than a curtain. and behind it space carries on as normal. It was these pirates who bothered to go around the Void to the other side, and find the systems there perfectly habitable.
They couldn't go through the Void, though, as it is fatal. Navigation is almost impossible due to the inability to see stars out of it. Worst of all is the possibility you might exit hyperpsace within the Void, which is a death sentence. You come out of hyperspace at very high speed, and the dense particles within the Void then shred your ship to pieces in seconds.
You never really had reason to go out that far- and in any case they are not pirates any more. In being descended from pirates, it is an Empire of harsh violence and absolute rule by their Emperor, a descendant of those pirates, but they make all their money from internal economy these days, rather than piracy. Mind you, apparently their taxation system is about as close to licensed piracy as you can get. Their tax collectors go around with small armies as bodyguards and, if necessary, battleships.
