Here we go, Calth girl has a name, Mirian Valerius, and a backstory.
Lady Mirian Valerius was born on Calth, not long before the devastating Battle of Calth. The fifth daughter of that noble family. Though her father was the head of the family, Lucius Valerius, and her mother Livia Tullius, was of similarly noble status, being the fifth daughter made her prospects rather distant compared to her elder sisters. Even if she did meet the Guillimans many times.
However, she did take full advantage of her ability to gain a very thorough education, studying everything she could get her hands on, not limiting herself to just what a noble lady should know. This brought her into contact with a young man known as Chairon. She was determined to learn as much about fighting as possible. Though he was reluctant at first, due to her being one of the very noble Valerii, they eventually struck up a friendship.
Though he had at first thought her a persistent pest, he found he actually missed her when she wasn’t around.
So he was actually getting worried when she suddenly stopped coming around. Without sending word, which she always did.
Before he could actually look for her, however, the Battle of Calth and the resulting devastation happened. And his thoughts turned to joining the Ultramarines and taking revenge on the heretics. Which led to him getting involved in Cawl’s Primaris Project.
On Mirian’s part, her family had found her a suitable spouse, so she was being sent off to marry a man she had never met. On Talassar of all places.
But what should have been a simple trip across the sector became a nightmare when the ship was caught in a warp storm. By the time they were spat back into real space, they had been displaced ten thousand years in the future, into a very different Ultramar.
Of course the Inquisition took interest, crew and passengers were thoroughly examined for Chaos corruption, not to mention equally thoroughly investigated for heresy.
Eventually released from durance vile, Mirian found herself on Macragge. Exhausted and confused, she went in search of answers.
To her surprise one of the first people she ran into was Chairon. Now a Primaris Space Marine. However, on first meeting she failed to jog his memory. To her disappointment.
Next, talking to Roboute Guilliman, the only other person whose name she recognized. However, this would bring her into contact with Cato Sicarius. Hopefully he was not a direct descendant of her would have been husband. That might be very awkward.
