An Inner Sphere system with no terraformation candidate. The central star, named Benes after an influential late Sundering era Jovian artist, is a young K-type star prone to flaring. In close orbit is a chain of five resonance-linked planets, extending out to the liquid water zone, which is occupied by Hanajri, a hot wet superterrestrial, and Atjen, a temperate SubNeptunian. Beyond the packed inner system were two Neptunian planets in distant orbits, shepherding a cold debris disk.

Benes was surveyed by the Lagrange Defenders, who then sold sections of the system to various groups. All of the polities within the Benes system were regulated by an overseeing entity known as the Benes Council. Originally, the Benes Council mostly existed to mediate conflicts between factions, but over time it evolved into a system-spanning federal government. In 1749 AT, the Council elected to join the Eridanus League, giving them access to a wealth of information that resulted in both local renaissances and rashes of ideological conflicts, although the Council successfully prevented these conflicts from escalating and causing widespread damage. In the attempt to gain political advantages, Benes quickly established extensive ties with its economically important neighbor Rana, the bonds that would persist even after the economic instability that plagued Rana in the 19th century.

The system joined the Taurus Nexus at the first opportunity, taking advantage of the wormhole link between Makintairas and Rana that was first opened in 2657. Anticipating the influx of new information to stir up societal problems, the Council also requested a transapient AIviser from Rana. The S1 transapient, known as Hii'i'swi'tok, migrated to Padsaro's depths. For the first few millennia, the transapient was reclusive, only interacting with the rest of the system as needed, but e would begin to play a more active role during the Central Alliance era.

According to the ex-Taurus Nexan folktale Kibfrey and Gorg, members of the Natural Order of the Taurus Nexus were exiled to this system. The fact that this story was fictional was well known among the inhabitants of Benes. However, the system did receive an influx of ex-Natural Order members (this was likely what the folktale was created to explain in the first place) who, during the Age of Separate Empires, eventually developed into the unique if short-lived Benes Nat Ord Dionys culture.

In 6492 AT the news of the emergence of the baroque Vore Abergist culture reached Benes. Over the next few hundred years, the mysterious culture grew into a sizable trading faction, trading exotic products from their designed gas giant ecologies for clarketech information tools. Although there was virtually no trade between the Vore Abergists and the inhabitants of Benes, the latter of which lacked clarketech devices, the aesthetics of this culture influenced many Benes artists, who began to decorate their habitats with an art style that can be regarded as an adaptation of the Benes patterns to fit the Abergist styles. Echoes of this art style can be seen in some of the older habitats to this day.

In 7521, the system was visited by the Inner Sphere Development Alliance, a Terragen Federation-backed initiative. Much of the system, while not opposed to the ideology of the empire, nevertheless politely rejected the invitation to join the Terragen Federation in favor of remaining independent. However, the general public's opinion of that empire improved, and the system was happy to seek closer ties with the empire.

In the Current Era, the Benes system has strong ties with both Rana and the Terragen Federation, but remains independent. Internally, it is split into 531 different polities that continue to be governed by the Benes Council, which by now has little in common with the original iteration of the organization. The majority of the embodied sophonts in Benes today live in hundreds of orbital bands spread all across the system, where most traditional centrifuge habitats had been replaced by microgravity habitats tailored to the preferences of the space-adapted morphs that have become popular in Benes since the 6300s. Others made their home on the moons of the planets, where access to space is easy. The skies of the planets are inhabited by polities of bubblehabs and their residents, most of which are among the more conservative of the bunch.

One of the more interesting cultures in Current Era Benes is the Yrakstrakk culture, centered at Alkengbi, where each individual always occupies two bodies, one on the planet and another in orbit around the same planet.
