== Valtamir-Yarres subsystem ==

Valtamir: a young DA1.6 white dwarf. Valtamir has a very faint planetary nebula surrounding it. Valtamir's worlds have very stable orbits, as they are all in laplace resonances.

Image Name Description Population
Tegris Tegris is a charred world, only around 5,000 km in diameter. The closest planet of Valtamir, Tegris has been through major atmosphere loss ever since it formed, especially when Valtamir threw off its outer layers and died around 90 million years ago. Tegris is still extremely hot, but does harbor many important materials. ~6,000 scientists and miners
Cerleor Cerleor is a deep red gas dwarf, constantly losing its atmosphere to Valtamir's extremely high temperature and solar wind. Like Tegris, it has gone through major atmosphere loss, starting out as a super-neptune but losing almost all of its old atmosphere to Valtamir. Only some of it remains, in the form of dark sooty clouds rich in alkali metals and alkali metals, which are extremely hot. ~1,000 scientists and miners
Kedro Kedro is probably the least interesting "planet" of Valtamir. It is the smallest planet, so small that it classifies as a dwarf planet. Kedro was always small, but it was reduced even more when Valtamir died. Now, Kedro is just a small iron core with a thin mantle above it. Very hot and tectonically dead, there is nothing very interesting about Kedro, other than its inclined orbit, which has been the result of many planetary interactions with the inner worlds and Azmodan. ~51,000 random people at all times
Azmodan Alongside Occamora, Azmodan may be the most interesting planet in the Valtamir-Yarres subsystem. It is a superterra, and measures 23325 km in diameter. This leads to a gravity of over 40 m/sec, the strongest gravity in the entire Valtamir system. Due to this, Azmodan has always had a thick atmosphere, but just like Tegris and Cerleor, it has been thinned drastically. Today, Azmodan still holds an extremely thick atmosphere, but it is no match compared to what it used to be like. When it finished forming, Azmodan was a great super-jupiter, many times Jupiter's mass. But as Valtamir died, much of the atmosphere was stripped, leaving only the very bottom layers still intact. These rose up and gave Azmodan a new atmosphere, and for the first time since its formation, Azmodan's surface was at least partly visible. Today, it roasts under the pressure of over 10,000 atm, mostly composed of hydrocarbons, which make an orange haze which stretches for hundreds of kilometres. Azmodan has 1 asteroid moon, Skolus, once the shepherd moon of Azmodan's long gone rings. ~14,000 scientists and miners
Occamora Similarly to Azmodan, Occamora is a superterra, and also a chthonian planet. With all of its mass under a sphere 20,967 km across, it is less dense than Azmodan, having a significant amount of its bulk made of water and other volatiles, including hydrocarbons. Occamora has a thinner atmosphere than Azmodan, which is mostly composed of water vapour, hydrocarbons and carbon dioxide, along with a global ocean of semi-supercritical, semi-liquid ocean of water and long hydrocarbons. Occamora was once a super-neptune in a 2:1 resonance with the early Azmodan. Now it exists in a 7:2 resonance, due to Valtamir's death destabilizing their orbits for some time. Occamora has 2 moons, which are:
  • Isaeon: Isaeon is as small as Enceladus, but it's quite hot and completely barren.
  • Etim: A captured, dark dwarf planet, Etim is effectively a quasi-moon, having an orbital period that is as long as Occamora's year.
30,000 scientists and miners
Dalnil The only gas giant orbiting Valtamir, Dalnil has been reduced to a sub-neptune through Valtamir's death. Its deep blue colouring is a hint to the violent world beneath the blue clouds. Large pieces of silica whizz through the clouds, racing around Dalnil in less than an hour. It is divided into 5 bands, two dark blue ones on a lighter blue backdrop, with many smaller white "scooters" between them. Dalnil is home to several mining operations, extracting silicon and other gases from its atmosphere. Dalnil has 3 moons, which are:
  • Tarhe: A moon riddled with volcanism. Although Tarhe has a thin atmosphere, lava lakes are everywhere.
  • Irinel: A steamy world, with a thick water haze and shallow, dark green water oceans, filled with impurities of iron. Irinel is a rejeuvenated moon, once habitable and is set to become habitable once again soon.
  • Keivlon: A hot mars-like world. Keivlon is riddled with sandstorms.
20,000 scientists and miners
Anurpen The furthest world from Valtamir, Anurpen was once a cool, small desert world with ice caps. It was dry, save for a lot of groundwater and large ice caps. Now, Anurpen has been terraformed by humans and it's a thriving ecumenopolis, a testament that not even the death of entire stars is enough to completely sterilise worlds. 24,520,000,000 inhabitants

Yarres: A cool red dwarf orbiting Valtamir every 16 years or so.

Aboll Aboll is a tidally locked rocky world orbiting Yarres. Nothing special about it. 14 million
Vetra Vetra is an interesting world. Earlier in its life, it used to have flowing liquid, likely water or ammonia. But when Valtamir died, these liquids were carried off with its outer layers, leaving Vetra completely barren. Today, only hints of these past rivers and lakes exist, peppered all across the planet. A terraforming project is under consideration. 33 million
