Position of Cronox in Syndicate space

Cronox [CRON-ox] is a S-type detached-binary star system consisting of the stars 1GD.Pa-Cordes and 1GD.Pb-Arjos. The two orbit a common barycenter at a sufficient distance for each to have its own independent planetary system. The two stars' orbital planes are at 83 degree angle from each other, which suggests that the two stars originally formed independently o…. The stars Cordes and Arjos are distant binaries, so on Helevos, Arjos is only seen in the northern hemisphere as star, sometimes bright enough to be seen during the day, circling roughly over the north poleplugin-autotooltip__small plugin-autotooltip_bigRetzayk

Retzayk is a long, narrow continent approximately 4500 km east of Anásthias, separated from it by the Redeeming Ocean. It extends from the North Pole, crossing the equator and deep into the southern hemisphere.

Comparison with Earth

Helevos is cooler than Earth, with the poles being much cooler. Comfortable range for human habitation is from the equator to 40 degrees north or south.

Due to oscillations in axial tilt and orbital precession, the world goes through a cycle of cooler and warmer periods lasting approximately 30,000 years. During the cooler periods, ice builds up on the polar continents, causing a dramatic lowering of sea level causing the land masses to grow in size. In the warmer periods ice melts, inundating low-lying land. This has a profound effect on human civilisation, with climate change and flooding regularly destroying the most advanced civilisations of the era leading to a generally low level of technology.

Helevos has six continentsplugin-autotooltip__small plugin-autotooltip_bigContinents

Anrel [ANN-rel], or the Anrel Isles, is the most northerly island group in the Natorn Archipelago. It consists of three major islands and numerous smaller ones. The largest, colloquially if infrequently called Mainland, is divided between the kingdoms of Trésard and Narette. The island HM is part of the Polassirn oceanic plate, but too small to be considered a true continent.

Opinion is divided as to the origin of this division, and indeed the origin of humanity. Though many religions have scriptural certainty that the world was divinely created, traditional opinion in the eastern world is that humanity is descended from an ancient race called the Godmenplugin-autotooltip__small plugin-autotooltip_bigGodmen

The Godmen were the mythical inhabitants of a landmass contiguous with the modern Natorn Archipelago, said to be the ancestors of all the Thalsic peoples of the northern Civilised World. In the Emerald Epoch they created the first great civilisation, referred to as the Realm of the Godmen. The Godmen are said to be mytho-historic, memories of an ancestor race shrouded by millennia of HartheraAnrelAnrelherherAnrelAnrel, who came to earth approximately seventeen millennia ago. The nature of the world and its hostile environment made it difficult to sustain complex technology, so that as humanity spread out across the world, civilisation gradually regressed to a primitive state. It has also meant that civilisation has so far been limited to one equatorial island continent, Anásthias.

The world has a highly evolved native ecosystem, which competes with an abundance of introduced and engineered species. It has two natural satellites, Theaplugin-autotooltip__small plugin-autotooltip_bigThea

Thea, or Theeya, is the larger of the two moons of Helevos, the smaller moon being Themsa.

Thea is a spheroid approximately 1582 km in diameter. I's surface is covered with an ochre iron-silicate dust with mountain ranges of lighter grey rock. In the night sky it appears as a disc less than half the size of Earth's moon, and much less bright. It's surface gives Thea a pinkish light in the night sky. a small spherical moon, and Themsaplugin-autotooltip__small plugin-autotooltip_bigThemsa

Themsa is the second and smaller of Helevos's two moons, the larger being Thea. Themsa is a small, silvery, potato-shaped body that spins through the sky on it's long axis, so that one rotation is the basis of an hour in the Hirèrk Moonscale.

Themsa was almost certainly a large, elipsoid asteroid that narrowly avoided striking the surface, and instead was captured in orbit. Themsa is roughly potato-shaped with a large crater visible at one end, the result of an impact that set the moo… an ellipsoid asteroid which rotates about its central axis and is seen spinning through the night sky. There are also four bright artificial satellites in geosynchronous orbits, known as the Fixed Starsplugin-autotooltip__small plugin-autotooltip_bigFixed stars

The Fixed Stars are the bright stars, more properly small moons, in the sky of Helevos. They are so called because they hold a fixed point in the night sky relative to the ground. There are thought to be four fixed stars, circling the heavens at the four quarters of the globe. Only three are visible in the skies of the.

Contact with Helevos is strictly prohibited by the Syndicate, in order to protect its native cultures.

Helevos is protected from solar winds by its intense magnetic field, generated by an iron core which is disproportionately large for the planet's size.

Its axial tilt is currently much less than Earth, so its axial seasonal variation is much less marked. However its more eccentric orbit creates a cycle of orbital seasons that have profound long-term effects. When axial winter coincides with orbital winter, winters are very severe and cause worldwide drops in sea level.

Helevos only has two small moons, and this has had important effects on the world’s development. Without being balanced by a large satellite, Helevos is much more prone to ‘wobble’, like a spinning top. Helevos’ tilt oscillates between 6 and 34 degrees over thousands of years. When tilt is at its maximum there are extreme winters at the poles. When these axial/orbital winters combine, several winters are enough to create polar ice sheets so thick that they do not melt. They cool the seas and reflect increasingly more sunset, triggering Ice Ages. This fluctation follows a cycle of tens of thousands of years. The world is currently in the middle of a warm interglacialplugin-autotooltip__small plugin-autotooltip_bigHirèrk Moonscale

The Hirèrk Moonscale [Hee-Rerrk] (HM) is a luni-solar calendar used at least since the time of Miyarris, which measures cycles based on the moons, solar years as well as the millennia-long cycles of global climate change. Today years HM are only seen in historic works and not considered accurate in historical accounts.HMHMBMEHMMEME.

Helevos has suffered many smaller collisions with iron-dense planetoids throughout its history, particularly during the formation of the binary star system, but it never suffered such a traumatic single impact. Subsequently the planet’s crust is relatively thick, so volcanic activity is relatively rare, rate of tectonic drift is slow.

Earth’s moon also stabilises the planet’s rotation.
