Hey, yeah please make a new thread for approved, so I can add them to the compendium without having to remove them from the How to Join the Sagan 4 Team thread
Fixed the typos
How does this elaboration on their internal structure sound?
How does this elaboration on their internal structure sound?

| While they still retain a larval state that is reminiscent of the ancestral [[gilltail]], they now spend longer out of the water as adults, growing a comparatively leathery epidermis layer that allows for moisture retention. They are also able to support themselves with a more rigid internal chitin endoskeletal structure, in a manor similar in setup to that of terran arthropods. This structure however in entirely internal and rather thin, resting directly between the dermal and epidermal layers of their skin, save for the skin on their tails. This structure is rather primitive and restricts growth, so this layer does not form until immediately prior to their emergence from water. Once this layer grows, they no longer grow in size. |
To reiterate, these species have until the end of the Generation 165 to be replaced or have a descendant move out, otherwise they will be lost

A rocky terrestrial ice planet that occupies the outer cold edge of the habitable zone of Sagan.
Sagan V receives approximately 75% of the solar radiation that Sagan IV gets from Sagan. If it were not for its large molten iron core, thats 60% of its mass it would not have had access to enough internal heat to support a near hospitable environment for liquid water. This heat source has continued to promote volcanic activity at near upper northern end of the equator at 10 to 40 degrees latitude. This zone harbours hotspots of volcanic activity that have created a cascade of atmospheric islands. The heavy carbon dioxide churned out by these volcanoes sinks to lower altitudes creating a blanket of warmer currents that produce their own greenhouse effect. A warming that brings temperatures up to 1.8 C maximum, thats enough to sustain liquid water.
These warmer zones are rare when compared against the vast majority of Sagan V's icy surface. The northern and southern poles are submerged under large glaciated areas where temperatures can fall to a minimum of 143K (-130C). The equatorial tundra although warmer than the poles, a temperature average of 208K (-66 C) is still too harsh for sustaining life (extremophile bacteria may survive it). This is a double-edged sword. The high albedo of Sagan V's ice-caps reflects large amounts of the little solar radiation it receives from Sagan. However, the ice melt at the equator (and near northern volcanic regions) are able to sustain a short-lived seasonal supply of liquid water with evaporation feeding water vapor into the atmosphere.
Although there is plenty of oxygen trapped in the form of water ice, it is not known whether their is sufficient atmospheric oxygen to support life in this cold environment.

Mason is a cold, foreboding world, as frigid as it is lifeless. It is composed mostly out of water ice and rock debris, and possesses a rocky core.
Mason is Sagan 4's only moon. It has a thick atmosphere (Titan-like) and no life on it (until the Bloodian Period).''
Like one gargantuan glacier, a single sheet of glacial ice covers the planet, precipitated by the little evaporation that does occur thanks in part to a slight heating caused by the moon's thick yet virtually transparent atmosphere.
What ice does melt and evaporate can make it into the upper levels of the lower atmosphere, where it can quickly cool and return to the surface as either snow or ice crystals.
Plate tectonics have been known to occur, but Mason has seemingly died in more geologically recent times, although it is possible that they have instead only calmed down to a fraction of their former activity.
These movements helped cause the massive trench-ravines that dot the surface - the largest of these can be seen even on the surface of its mother planet, Sagan 4. What was initially craters caused by large asteroids striking the surface was facilitated by the tectonics, resulting in great expanses of surface ice buckling and crumbling into the abysses subsequently created.
The largest of these trenches, occasionally nicknamed "the eyes of Mason" or "Mason's stare", extend so far below the regular surface that general scans cannot judge its actual depth. It is possible that this trench drops all the way to the moon's mantle, although it is unlikely that it drops as far down as that. But they do appear to still be massively deep. Depending on the thickness of the glaciers, they could be miles upon miles deep.
The old tectonics of the world have also caused massive mountains to be raised, upon which large formations of clouds dash themselves, constantly dropping great amounts of snow and ice upon them every year. This growth is enough to keep the glaciers upon these ranges as a permanent feature, like the rest of the world.
Significant cloud cover does not form often due to only minimal amounts of evaporation, and also due in part to the wind routes, which can disperse what exists of clouds over larger areas, making the existing evaporatory substances far less prominent in the skies above.
Despite the lack of true cloud cover, Mason's atmosphere is heavy and thick, consisting of large amounts of nitrogen, oxygen, argon, radon, xenon, and very small traces of dispersed gaseous iodine.
Lightning storms are quite rare on Mason, but have occurred in the past. These storms can be brilliant in color, thanks to the abundance of noble gases in the atmosphere. Lightning therefore has been known to cause the local area to glow purple or even bright blue for a split second when the atoms are excited by the electrical discharges. As stated before, however, this is a rare sight.

A rocky (desert) terrestrial planet occupying the inner edge of Sagan's habitable zone.
Sagan III's 15 degree axis tilt allows more solar heat to fall on its poles preventing any snow fall from creating polar ice caps. Even though temperatures can fall to 262K (-11C) during the colder nights their influence is canceled out by the hotter diurnal temperatures.
The equator is a hellish super arid landscape baked throughout the day by scorching temperatures reaching up to a maximum of 361K (88C) by midday.
Most of the volcanic activity on Sagan III is dormant except at near equatorial regions. It is not clear whether the superhot equatorial climate has encouraged more volcanic activity but since this is the only region where it prospers it is assumed that higher temperatures have promoted the geological activity here. Adequate magnetic field generated by its iron core and a moderate atmosphere have provided protection from solar winds and prevented a runaway greenhouse effect.
Volcanic dust from eruptions carried way by winds to replenish desert sands below polar latitudes are darker than the equatorial brighter sands. This difference in sand brightness has lead to a higher albedo at the equator and lower at higher latitudes. The darker sands absorb more heat while the lighter ones at equator reflect it more creating a significant temperature difference at higher atmospheric altitudes. This temperature potential coupled with the high rotational spin of Sagan III has helped to nuture the vigorous winds that transport hotter equatorial air and dust to higher latitudes. The volcanoes are the only source of water output on Sagan III. Gaseous matter, including water vapor, ejected during eruptions is speedily carried way by the winds. This heavy mix sinks to lower altitudes, where the water vapor condenses as a dew during the colder nightly periods on the darker sands (higher latitudes). The sands absorb the dew, a slow water drainage process given the small volume of water at the surface. A vast water table has evolved over many millennia at these latitudes. Thats vast for Sagan III's arid landscape but would be considered as a poor supply by Sagan IV standards.
Tolerable temperatures of 30 to 40C are reached at higher latitudes. The southern regions are covered with long sand dunes that rise ten times higher than those on earth. The northern areas are hosts to vast desert plains where dust devils regularly stir up multiple miniature sand storms. When these merge large sand storms form, affecting the movement of sand dunes at south. These very high sand dunes act as natural barriers that contain the sandstorms preventing wide scale spreading. The water table is also at its deepest here. Life could prosper here assuming the moderate temperatures remain stable.

A rocky terrestrial planet with a runaway greenhouse atmosphere.
Sagan II has a thick, impenetrable atmosphere, dominated by carbon dioxide and sulphurous materials. Sulphuric acid clouds churn away in the turbulent atmosphere, creating huge frictional forces that are released as powerful lightening storms. These clouds condense to form acid rain, which evaporates before it can reach the surface.
Chains of dome volcanoes reaching up to 10km high and 300km long meld into each other to form long volcanic plains and valleys. Pouring out enormous amounts of carbon dioxide and sulphurous materials. Lava flows from these have created huge lava oceans that are regularly replenished. The cooling lava approaching solidification is quickly eroded away by acid rainfall that helps to form long tentacled channels, conduits for fresh lava flows. Large columnated structures are carved out by the very dense atmospheric winds. These form canyon like regions as well as intricate features that look like abstract architectural sculptures that pop in and out of existence under the accelerated weathering conditions of Sagan II.
Sagan II is much more closer to its sun than Venus thus experiences an even more heightened greenhouse effect. Surface temperatures soar from a minimum of 382K (109 C) to a maximum of 832K (558 C). It has a large axis tilt of 34 degrees causing more temperature fluctuations. Its high orbital and rotation speeds of 49.2 and 410.5Km/s further add to its tumultuous climate.

These form canyon like regions as well as intricate features that look like abstract architectural sculptures that pop in and out of existence under the accelerated weathering conditions of Sagan II.
Sagan II is much more closer to its sun than Venus thus experiences an even more heightened greenhouse effect. Surface temperatures soar from a minimum of 382K (109 C) to a maximum of 832K (558 C). It has a large axis tilt of 34 degrees causing more temperature fluctuations. Its high orbital and rotation speeds of 49.2 and 410.5Km/s further add to its tumultuous climate.
This topic is to talk about the information regarding the first planet of the Sagan system - Sagan I.

Rotation Period (Its day): 24.67 Earth Days
A small sterile rocky terrestrial planet very close to Sagan star (0.23 au).
Sagan I's close proximity to its host star has resulted in complete loss of its atmosphere. Its iron core has become solid and no longer radiates heat thus Sagan I is considered to be geologically dead. The small magnetic field produced by its iron core is not strong enough to shield the planet against Sagan's solar winds. Any remaining atmosphere has been stripped away by these solar winds.
Sagan I has a fast orbital and rotational speed of 69.9 Km/s and 496.5Km/s respectively. These speeds have given it a peculiar feature, a year and a day approaching the same period (year: 35.59 earth days, day: 24.67 earth hours). The temperatures on Sagan I fluctuate rapidly over a single day. Regular exposure of its surface to heavy solar radiation super heats it to 401C during the day whilst experiencing freezing temperatures during the night (-138 C). This is because Sagan I does not have an atmosphere or internal heating (dead Iron core) to keep it warm during the night cycle. These shifting extremes in temperature have produced a rubbled cracked surface covered with many impact craters.
A major distinguishing surface feature of Sagan I is a huge crater along its northern equatorial latitudes. Spanning almost one quarter its own diameter, pock marked with many impact craters along its perimeter edge, resembling a yawning toothed mouth. It is believed that a collision encounter with another rocky body in it's distant past may have been responsible for its large axis tilt of 32 degrees. This may also have brought it in closer proximity to Sagan star. A death hug with its host star that stripped away its atmosphere and lead to its current sterile existence as a burning planetary cinder of extreme heat (day) and intermittent freezing(night).

Rudi10001 I'm sorry but I'm going to have to reject this idea. It violates a number of project rules we have, including our strict restrictions on sapient creatures. Please read our Submission Rules thread before making another attempt.

But yeeah these both look good. Approved
Hey, so I merged these two topics, since they are functionally the same
