Dimostah is the smallest planet of the Saihera System and the capital of the Kingdom of Saihera. The planet holds a very special place for the Scargass species, although it is not their original homeworld. After the supernova of Tegerelis, a few thousand Scargass escaped the blast and the destruction of their home planet and fled to the nearest world that was habitable to them, Dimostah. This essentially makes the planet the honorary homeworld of the species, although it has essentially no native life. Dimostah is also very important to the Kingdom of Saihera as a whole, as it is the seat of the royal family and the government of the Kingdom.
During the War of Saiheran Succession, Dimostah was ruled personally by Prince Sais Atherian, as she transformed the planet into a massive military compound to protect against attacks. During the war, the population of the planet suffered greatly under his iron fist. He instituted martial law on the planet and indefinitely imprisoned and tortured anyone who spoke out against this. However, upon her death at the end of the War of Saiheran Succession, the planet was freed, and there was a massive celebration. Many refugees from the planet returned as well.
Dimostah is incredibly small and is at the low end of the planetary size range, so some consider it to be a dwarf planet. It is similarly tiny in mass, having less than a fiftieth of a standard terrestrial mass. Unlike most capital worlds, it has almost no native life. Aside from this, Dimostah is very habitable to certain kinds of life, as it has abundant oceans of liquid methane and ethane covering large portions of its surface. Dimostah has a weak natural magnetic field, although it was strengthened by a specially built orbital ring which generated a stronger one, due to a primarily icy composition. Beneath a 100 km or so icy crust, there is a sterile liquid water ocean. Beneath this there is another layer of exotic pressurized ice, and finally beneath that is a rocky core.
The atmosphere of Dimostah is very thick and is composed primarily of nitrogen. It also has a decent percentage of methane, due to evaporation from the large oceans of the planet. There is also trace amounts of hydrogen and other gases.
Dimostah's atmosphere has differing compositions depending on altitude, as in the troposphere there is more methane than above this zone. There are also large-scale haze layers positioned hundreds of kilometers above the surface of the planet, making for some very beautiful views of the endless orange clouds beneath.
Orbit & Rotation
Dimostah is an outer planet of the M-type star of Saihera, and is located in the methane temperate zone. Thus, it escapes the tidal locking of the inner worlds of the system, giving it a more-or-less normal day and night cycle. The eccentricity of Dimostah's orbit is rather low.
Dimostah rotates once every 32.5 hours. This combined with its low temperature gives it sluggish upper atmospheric winds, making the haze layers more stable. However, Dimostah's axial tilt is very high, at 71.7 degrees, meaning that parts of the planet are in darkness for years at a time.
Dimostah is considered to be a lacustrine world pocked with small hydrocarbon lakes. There are few bodies that are not small enough to see clear across, and as such the vast majority of the planet's surface is land-based.
The largest lake on Dimostah is Lake Krazal, a massive lake on the south pole covering more surface area than the next ten combined. The royal palace and government buildings are situated on an island in this lake.
Dimostah has an interesting climate. Due to the fact that the planet's thalassogen also makes up a large portion of the atmosphere, the actual pressure is rather variable as it rains out and evaporates back up. This unique property can make for some interesting weather patterns.
There are few actual clouds on the planet, but the atmosphere is always colored an opaque orange due to a dense organonitrogen haze. Clouds typically cover 1% of Dimostah's disk, though outburst events have been observed in which the cloud cover rapidly expands to as much as 8%. Large banks of southern clouds are formed when heightened levels of sunlight during the southern summer generate uplift in the atmosphere, resulting in convection.
Dimostah used to have a large set of captured asteroid moons, but unfortunately all of them have been disassembled to construct various bits of orbital infrastructure. None of them were very interesting anyway.
