Sunburst Interstellar

Sunburst Interstellar was named after the Nubian Interstellar popular transport, the Sun Burst. It was originally a public transportation agency in one of the nations that predated the formation of the, now large galactic factions. 
The Sunburst is mostly retired now, and the Rimstrider Mk V is the current most used interstellar passenger craft, ironically the Rimstrider has always been the favored choice of Sunburst's greatest rival, Rimstrider Multistellar. 
Sunburst became the greatest transportation agency in the known galaxy when they secured rights to travel into the, at the time, mysterious Triumvirate space reaches, and Rimstrider took the name "Multistellar" instead of "interstellar" as a result. 
Sunburst still only uses Nubian crafts - they lose a lot of customers to the cargo transportation companies that tend to take along passengers as a side business for a pittance compared to the going rates for a Sunburst trip. 
Sunburst offers more affordable trips on military patrol crafts in all of the known space regions, which is a concept that has won a lot of popularity. 
Even though Sunburst's own transporters are extremely well protected.
