The Bringal system is unusual. Unusual enough that some suspect the system to have been manufactured in some way.
A massive gas giant orbits near the sun, known as a ‘hot Jupiter’. This itself isn’t what makes the system unusual. The first thing that makes the system unusual is that the gas giant is inhabited. The inhabitants, known colloquially as ‘star whales’ are massive, semi-draconic life forms. Little is known about them save that they are clearly of high intelligence and appear to have several life stages. During at least one of their life stages, they are capable of not just surviving but actively thriving in vacuum. From time to time ships encounter them swimming in the far reaches of space.
It is possible Bringal is not their home system, but merely a colony. If that is the case, then their origins are entirely unknown. They are, however, not the only odd thing about the Bringal system. The gas giant itself hosts no fewer than four inhabitable moons. Additionally, on the other edge of the habitable zone are two more habitable planets, with the smaller one orbiting the larger.
Furthermore, examination of the life forms found on these planets would indicate that they are not native to the system themselves. It is theorized that for reasons of their own, the star whales built the system and used it to house life forms collected from other worlds. Some think that the Bringal system is the star whale equivalent of a zoo, while others think that the star whales may have been collecting species that would otherwise have died out or been destroyed.
Thus far, the star whales have not shown overt signs of hostility. However, if threatened, they have proved capable of destroying warships with very little effort. They seem willing to allow ships into the system as long as the ships do not engage in hostility themselves. As such, the Bringal system serves as an effective neutral zone. Unfortunately, it also serves pirates as a safe haven, though it is worth noting that particularly vicious pirates that try to use the system as a refuge often simply vanish. Perhaps the star whales handle the matter themselves?
