evolves first as microbes before it becomes complex creatures like us and the Shaitans.
Earth microbes carried specific molecular machinery, which attached to specific parts of our body and released specific proteins that attached in very precise and specific ways to our own body proteins to create a reaction. Some were helpful to our bodies, while others were harmful. This specialized and precise molecular machinery had developed over billions of years for all the Earth animals and plants evolving together.
The Shaitan microbes also had molecular machinery, but they were so alien compared to ours that when an Earth animal, including humans came in contact with those microbes, they ignored each other and passed off as inorganic, inanimate objects, like tiny bits of dust. The molecular machinery had no way to attach to each other.
Violet and most microbiologist on Earth were confident that due to this vast disparity in the molecular machinery, humans were not in danger of alien infection. However nothing could be said for certain. Microbiology was treading into unprecedented and unknown territory. No one could know the long term effects of exposure, it would have to be observed over years.
During normal times, biologists and immunologists would have recommended years of isolated study on Shaitan germ cultures. Slowly testing them from lower animals to higher ones, then mammals and finally on human cells before allowing even a single human to come into contact with those Shaitan microbes.
These were however not normal times. These were times of war. Not just any war, a war for the survival of human species. Humans took higher risks during times of war, and short circuited many procedures. Violet had submitted her final test reports to Earth after 22 days of non-stop work. She had finished every test that was possible with the resources she had on Titan.
While nothing harmful had been detected, and the theory said that nothing could be harmful, there were many more test possible and even necessary to confirm safety of exposure to the Shaitan bugs, but all of those would require equipment and cultures not available to Violet on Titan. So the military and the political establishment had to make a decision.
They could wait years for samples to be transported and studied properly on Earth. Scientists were however recommending that the Shaitan bugs should remain isolated on Titan, and testing equipment should be sent to Titan and all tests carried out in the sterile atmosphere of Titan. Both the options meant waiting years, perhaps as much as 5 years before proper access could be had to Shaitan technology.
Some work could be done by scientist using suits, but it would be severely limited. The scientists and technicians would eventually get exposed to Shaitan bugs working in suits anyway within a few weeks. The suits will have to enter the human camp, and the outer skin of the suit will be touched by human hands.
So a decision was made, which many would find unethical, but extraordinary times call for extraordinary measures. In a way, the surviving members of the Titan expedition were to become guinea pigs. They would get exposed to the Shaitan bugs by working in the Shaitan habitat without suit.
The team would be isolated on Titan for another 10 months, after which they would be on board a space ship for another 10 months. The returning expedition and the crew would be kept in isolation for another 4 months. This would provide 2 years of observation on human subjects. This was enough as far as humans were concerned.
If the Shaitan pathogens were harmful to humans, they needed to know as fast as possible. It would open a completely new vista of warfare possible – that of biological warfare. Humans would have to prepare for it as early as they can. Conversely if the humans could study the Shaitan biome, then perhaps humans could design pathogens to wipe out the Shaitans.
While this was never officially stated, since it
