Jarilo

Jarilo is a system on the Spinward edge of the Zorya sub-sector.

Zintau Morle Loni Cale Shami Kalle
 * Physically, Zintau is a rocky terrestrial class world. Although it once had prominent mountain ranges and active volcanism, all of these are things of the past now. Due to its great age, the mountains have eroded away. The tectonic plates have fused and become inert. All that remains is a vast layer of water ice and a very thin atmosphere of heavier elements and compounds that is no longer breathable.
 * Morle Loni is an Earth-like planet. Much like Earth, the landscape is weathered and suffers from extension weather related activity including massive storms and erosive oceans. With varied biospheres ranging from hot and arid to cool and wet, Morle Loni has an abundance of geophysical features. In orbit are two barren moons, often called Morle and Loni.
 * An ugly planet, Cale is pock-marked by extensive impact cratering across the entire globe. The atmosphere is almost unbearable for human life, with a very low concentration of oxygen contained within it and a surprising amount of carbon dioxide mixed with nitrogen. The planet has no native lifeforms, but there is an abundance of potable water contained in rapidly flowing rivers that seem to be polluted with all manner of alluvia and grainy detritus. Overall, the impression given of the planet is one that is not entirely hospitable to life, even if it is inside the habitable zone of its parent star.
 * Shami is a planet orbiting Jarilo. Slightly beyond the edge of the habitable zone, the planet is a frosty orb punctuated with large craters, mountain ranges, several major plateaus and maria. Geo-physically, the most prominent feature is a long ridge that extends over half the way around the planet that connects one of the higher plateaus on the far side to the lower lying lands on the other.
 * Kalle is a gas giant that orbits at a far distance from its parent star, Jarilo. In terms of mass alone, it most closely resembles Neptune in Earth’s own solar system. But therein the similarities end. The most striking feature of Kalle is its atmosphere. Enriched with gases such as Xenon, Helium and other noble gases, Kalle is a valuable resource that begs to be harvested for the raw materials that it can provide to the wider Galaxy. Given how calm the upper atmosphere is, Kalle is a prime example of a gas giant that is very old and has almost finished its gravitational contraction. Indeed, unlike other Neptunians, it receives more energy than it gives out - a tell-tale sign that it has just about contracted as much as it ever will (although some further contraction is likely, it will not be heating the gas giant more than the light it receives from Jarilo).
