Jamie was the only person Zerrin had recognized as his Brother, they may not be connected by blood but he was the man he most depended on when he roamed the battlefield. On four separate days he had saved his life through his sheer willpower and stupidity. He was the complete opposite of his calm, collected, and clever sister, though he was a great deal politer than her.
Jamie was from a small scale sect known as 'Mountain of the Bloodied Star' which is usually shortened to the Bloody Star Sect, much to their chagrin. It only had a few hundred members but it was easily one of the most terrifying existences in the area, as their training made their members fearless and ruthless, easily capable of taking on the skies above if they weren't so cowardly.
Jamie and Marlev seemed to be a match made in heaven, and had been trying for a child for a while. It was a shame that Marlev's Nexus broke during Arc's birth, she had always wanted a blood family member. If he had been even an hour earlier he might have been able to seal it before she lost too much of her core energy.
In her dying moments she used the last energy remaining in her to divine his Stellar Name, the name the Heavenly Laws identified him by. Most people would never learn their full Stellar name, usually only the third or second star which were the weakest, as the Heavens would fight tooth and nail in order to keep this identity secret. The most common way to learn of them was through enlightenment or breakthrough where the Heavens would present a star to the individual that corresponded to one of their names.
Of course this didn't always mean they were useful to advance, there were nigh countless stars in the sky and not every one of them had been identified and had their corelated path identified. Arc's name for example, Colaris Dominus Arcturus, was not identified at all as far as Zerrin knew. He had spent the months since her passing requesting the assistance of many people, including the very man who founded the Blank Silver Sect, to help with the identification of even just one of the stars but to no avail.
Of course this didn't mean that there was no benefit at all to a cultivator knowing their own stars but not their respective paths or locations. Those who knew at least one of their Stellar names would find that diviners and oracles would have a greater degree of difficulty ascertaining any information about them. It was speculated that those who knew their full names would be able to hide their location and future from even the Heavens themselves, though there had never been a case of one finding all of them.
Tertiary names, or the third of the names, were by far the most common to know. This didn't mean they were particularly common, in fact they were exceedingly rare, but about 90% of those who knew one of their names knew their tertiary name.
Secondary names were the next common, but still rarer than tertiary names by about a factor of ten, meaning about 9% of those who knew one name knew that one.
Primary names were the rarest of all, even rarer than those who knew both their secondary and tertiary names, so putting them as a percent of the population of those who knew at least one was not enough to be counted in that way. It was highly likely there was only less than twenty such people in a world with a population hovering somewhere in the billions.
Marlev had used a bloodline art in order to accomplish this feat of revealing all three, using her skills as one of the top diviners on the continent combined with her limited blood energy reserves in order to reveal her son's Name to her at the moment the Heavens bestowed it upon him. Even if her Nexus hadn't broken, this action alone would have drawn down judgement from the Heavens in order to keep the name a secret.
Regardless, Marlev played the Heavenly Rules, using her quickly fleeting life as the bargaining chip to ensure her son's safety. Zerrin had done a test and concluded that the child was completely immune to divination, he would be safe from any enemies that would attempt to get revenge on her through her offspring.
Jamie, the man currently knocking on his door and interrupting him from his search through the star charts, knew nothing of this information and had instead blamed himself for her death. He had been cursed very early in his life by a Vile Cultivator to never have offspring. Of course this curse had been easily removed by his elders and had been confirmed removed by Marlev herself, but he still felt that this was the price he paid for it and loathed himself deeply.
Sometimes Zerrin wondered if she had ruptured her Nexus on her own as she seemed too well prepared for the event and couldn't help but remember her cunning side. However he ultimately dismissed that conjecture as extremely unlikely, ever since she was young she had talked to him in secret about wanting to have a child when she grew up and how she wanted him to be that child's uncle and shower it with gifts and attention.
She wanted to live a peaceful life in the countryside with a husband who would cherish and provide for her while she worked around the house, cleaning, cooking, weaving, and reading as she saw fit. These were all comforts of life she had never gotten to experience before, and just as her dream was about to come to fruition she died, never getting to hear the laugh of her kin.
He was disturbed and greatly angered at this, she had suffered far too much in her life to die to something as rare, painful, and drawn out as a prenatal Nexus break in which the presence of the baby made it impossible for the parents to seal the cracks and tears. He had decided the moment he arrived that he would do absolutely anything and everything to ensure that that child, Arc, would survive the trauma of a malnourished Nexus after birth and live the life she was never able to.
The only thing going through his mind as he went back to the site of her demise was that he would fulfil that final promise to her even if it cost him his life.
