Saros is a callous and selfish person who has no personal relationships, and very few allies. He would rather help himself and observe people from a distance than actually engage with them, and regards people who have an interest in him with great suspicion. Contrary to what most would conclude, he does not hate people, and will sometimes find himself invested in the lives of others from a distance. Unfortunately due to his upbringing, he often fails to understand cultural contexts and the complex emotions of others. No matter how much he can watch people, he knows he will never truly understand what it is like to just exist as other humans and species do.

Saros was raised in the slums of a highly advanced planet whose primary export were human soldiers and weapons. His parents worked in the factories, and he lived a simple and quiet life as an only child. When he was a young teenager, he was selected from the lottery to become a soldier, and he left home to train.

Due to his exceptional health and academic skills, he became part of one of the many super soldier projects. The project's goal was to biologically incorporate space travel technology into the soldiers themselves, creating cyborgs who could travel space without needing ships or stationary teleportation devices for transport. The project was promising at first, but began to fail over time. Many of the soldiers died from terrible side effects and accidents in the lab and out on the field. Saros, however, was surpassing expectations.

The project was dissolved, and Saros was subjected to the final steps of being conditioned to become a perfect soldier. The clinical settings, the social isolation, and the cruel reinforcements of certain behaviors left him numb to what it meant to be human at all. At this point, he could barely recognize his own reflection, or remember the names of his parents.

Eventually, he was released into the field with one other soldier he worked closely with. This person was also subject to experiments like him, but did not experience the same success. The two of them bonded to a degree, but his friend was suffering greatly at the hands of the experiments inflicted upon him. It didn't take long for his body to fail entirely, and Saros, out of rage and sorrow, escaped for the stars.

He now spends most of his time fleeing the federation, and making side money by stealing from unsavory ruling class members of society. Sometimes he fins a place to stay long enough where he rents out a small room to live from, but typically he has to be almost constantly traveling to avoid being found. Sometimes he spends long nights on rooftops, watching the lives of the people around him, and hoping to one day remember what it was like to be human.
