Since there is a massive worldwide forest that is continually producing oxygen, I don't see this as an absolute show-stopper. But my suggestion was that Perrein's ionosphere might have a composition such that it does a better job of forming an induced magnetosphere, and thus slowing the loss of water vapor and other volatiles. Contrary to your assertion, Venus is able to keep its ionosphere from being blown off without a magnetic field.Cthulhu wrote:That's what I'm talking about.Arioch wrote:Except that Venus' ionosphere does exactly that. Venus has roughly similar size, mass, and distance from its primary to Perrein, and also has no magnetic field... yet it retains an atmosphere 90 times more dense than Earth's.Cthulhu wrote:That's exactly the problem. Without the shielding from the magnetic field the solar wind will blow off the ionosphere, then wreak havoc on the lower levels as well as on all life. The ionosphere cannot induce its own magnetic field to hold itself in place.
Titan also has no (known) magnetic field, and yet manages to retain an atmosphere more dense than Earth's.
Venus has an atmosphere due to its sufficiently powerful gravitational force (unlike Mars), but because it has no magnetic field, this atmosphere consists mostly of CO2. Venus' ionosphere is, unlike Earths, not able to withstand the solar wind and all light gases are blown away. An induced magnetosphere is not powerful enough to contain it. By this point, only trace amounts of hydrogen and oxygen remain, but those can still be found in Venus' trail, which confirms the still ongoing erosion.
The Loroi have a shared martial pre-history, as reflected in their mythology, and so most Loroi social systems tend to have a martial flavor to them. Those that were less militaristic tended to get taken over by those that were more so. There were examples where physical isolation led to the survival of such systems. One would be the southern Amenal islands on Taben, who were less martial than their northern neighbors in Beleri. Like the vikings, Belerid Loroi would raid and sometimes conquer Amenal settlements, but often became subsumed within the "conquered" culture. Another would be Perrein, where terrain made distant city-states somewhat remote from one another, and allowed for greater diversity of cultures. Notably, some of the Perrein systems were based on religion, though the last of these was wiped out in Perrein's atomic wars. But the one feature that all (non-barbarian) systems needed to have in common was some kind of population control, and in ancient times the most effective way to accomplish this was with some kind of restricted alpha breeding system.Cthulhu wrote:As how I understand it, the current Loroi social and political structure is rooted in the old warrior caste and clan structures. In ancient times it was necessary in order to maintain population control. It was the only way to maintain order and advance as a society. Or was it? Were or are there any other schools of thought on how Loroi civilization should be organized? How are such ideas received?
In the present, not all Loroi subcultures are as military-oriented as the Sister Worlds. Maia being a prime example of a society more developed around free markets, rather than the state-controlled mercantilism that militarists tend to prefer.
