The Helyar-Byutix System is a major binary star system located in the Via Sagittaria Galaxy. The Helyar-Byutix System is comprised of the two stars, Helyar and Byutix, the latter of which orbits at a far distance from Helyar. The Helyar-Byutix System is most notably the home system of Humans which evolved on one of its planets, Aegyn. Currently, there exist 14 planets in the Helyar-Byutix System, with a majority, eight, appearing around Helyar. Byutix on the other hand holds six planetary bodies.

Architecture

The Helyar-Byutix System, to its innermost parts, holds five planets. namely, these planets are Shosturan, Icaron, Vyrullian, Aegyn, and Olaris. In the outer Helyar System, there are three gaseous worlds, which are Sakurelle, Exriel, and Zepyai. Beyond Zepyai lies an assemblage of various debris, space stations, and sparsely inhabited areas known colloquially as the Celestial Junkyard. Beyond Helyar's confines lies the Byutix System, which, as previously mentioned, holds six planetary bodies. They are listed as Simud, Heuser, Kashish, Azaa, Delkash, and Orethus. Sprinkled through the entire system, there are many stations which hold a massive portion of the population of the system.

Planetary Bodies - In Detail

Shosturan

Brief Description

Shosturan is the first major body in the Helyar System, and exists as a scorched gaseous planet, orbiting very close to Helyar. Typically, Shosturan is known for its striking and unique appearance, as well as its network of mining arrays around the planet itself. Shosturan has no current moons, with all of them being stripped away and used for resources. The remains of any former moons have been formed into a thin dust ring. This ring will likely be blown away by solar wind within the next one hundred thousand years. Shosturan was known for being notably profitable in terms of resource extraction.

Shosturan has been thoroughly harvested for resources to the point that only molecular hydrogen and helium remain. Even isotopes such as Hydrogen-2, hydrogen-3, and Helium-3 have since been exhausted. In terms of materials, all that remains are common silicates in the core. It has been this thoroughly harvested since the days of the Yohjan Confederacy, the original nation to control Shosturan.

Icaron

Brief Description

Icaron is the second planet in the Helyar System. Due to its incredibly high temperatures (well over 1200 C) and incredibly thick atmosphere, the planet is partially covered in molten rocks. The planet is fairly resource-poor and is mostly made of silicates. With no volcanism taking place within the last several million years and the highest mountains melting over time, the planet is remarkably smooth, with variation of less than ten meters across the planet. It has an atmosphere made mostly of carbon and sulfur dioxides that has been slowly escaping it, without outside intervention, the planet will end up with no atmosphere within one billion years.

The planet is the site of various small settlements deep underground, closer to the cold, dead core. Currently travel via its several orbital rings is preferred. It has a population of less than ten thousand.

Vyllurian

Brief Description

Vyllurian is the third major body in the Helyar System, and exists as a deep oceanic planet, scalding to humans at the equator, but pleasant at the poles in winter. Vyllurian is hot enough to make most Aegyn-born humans very uncomfortable after being on the planet for just a few hours. Floating cities on the surface often have cooling systems to prevent heat-related fatigue. The hot water makes Vyllurian into an somewhat popular tourist destination. Its known colloquially as the 'Planet-wide hot spring' and is rumored (although the veracity of such rumors is questionable at best) to have healing properties for those that bathe in it.

Vyllurian has a large number of photosynthetic bacteria within its waters. In more shallow areas, the water even appears slightly green. These bacteria were genetically modified to supply oxygen for the inhabitants. These bacteria are much more sparse in the deep equatorial waters.

Aegyn & Olaris

Brief Description

Aegyn and Olaris orbit each other in a very close binary, becoming the fourth major body in the Helyar System. Olaris, while being slightly less massive than Aegyn, is also slightly larger. The tidal forces between the two have caused them to be tidally locked with each other, a trait that served the construction of a space elevator between them. Aegyn is the homeworld of humanity, with Olaris being the first world humans colonized.

Life first emerged on Aegyn 4.0 Gya. While never emerging on Olaris by itself, human probes landing on the body brought life of their own to the body. Within centuries of these probes landing, Olaris began having traceable quantities of oxygen in its atmosphere, despite terraformation having not started yet. Olaris was easily terraformed by 18,900 BCE. In 15,089 BCE, Aegyn became the capital of the Yohjan Confederacy and for the next 15 millennia, was essentially the center of the galaxy. Today, the two planets lie in ruins. Abandoned after the collapse of the Yohjan Confederacy. Aegyn and Olaris have been derelict worlds for millennia. Only recently did recolonization efforts begin in 91,000 CE.

Sakurelle

Brief Description

Sakurelle, the fifth body from Helyar, is the indisputable jewel of the system. The swirling amaranth clods and massive cobalt rings are some of the most striking features of the system. It is the second largest planet in the system; only Exriel is larger. However, Sakurelle is known for its incredibly powerful magnetic field, which is strong enough to create massive aurorae on itself and the largest few of its moons.

Sakurelle's moons are among some of the strangest around Helyar. Oceans of methane exist on its closest moon, Svaelamr. Caewyn, a small gaseous moon barely larger than Vyllurian, is often called 'Sakurelle's Heavenly Knight' and is a rare gas dwarf moon. Sakurelle's only habitable moon, Nusti, has 2 submoons.

Sakurelle is the economic heart of the Helyar system. Countless commercial O'Neill Cylinders float among the rings, offering everything from advanced everyday technologies to high-end real estate. No matter what one may wish to buy, it's likely being sold from around Sakurelle.
