Katya Blackheart was the eldest child of Russian immigrants who had built a quiet, practical life in Atlanta. Her father was a carpenter. Her mother was the kind of woman who solved problems before other people noticed they existed. Katya took after her mother — she had an instinct for reading situations and a blunt, physical confidence that made her well-suited to work that didn't have a clean professional name. By her mid-twenties she had established herself as a tracker and retrieval specialist, the person neighbors hired when something needed finding and discretion mattered more than credentials.

She was not home when the meteor struck. She returned from a job in Mississippi to find Atlanta coming apart — the sky still faintly green, fires burning in several directions at once, and the particular social violence that catastrophe tends to unlock already underway. The men in white robes who attacked her family's home were opportunists with old grievances and a new excuse. Her father died in the fire they set. Her mother died in the street. Katya fought and lost and woke up in the snow beside her mother's body with wounds she shouldn't have survived, and something green threading through the blood beneath her. The power that rose in her that night was not a gift so much as a response — the world had changed the rules, and her body had changed with them.

Her brother Yuri was the only family she had left, and she lost him within days. He had developed something too — a fire that he didn't yet understand — and he tried to use it to heal her. It consumed him instead. He died quickly and told her he loved her while it happened, which was the worst possible version of a last thing to say to someone. She buried what she could bury and left Atlanta with Reginald, her blue heeler, and the clothes she'd worn on the Mississippi job.

What defined Katya going into the events of the Wendigo Campaign was less the grief than the practical orientation she maintained despite it. She had lost her entire family in the span of a few days, acquired magic she hadn't asked for, and kept moving — not because she had processed any of it, but because stopping wasn't something her nature allowed. The anger was real and close to the surface. So was the competence.
