Seren Sato, middle name Keladry, is one of three children rescued as infants/fetuses from a Torchwood badfic. She and her siblings are written by Zingenmir.
Seren was rescued as a fetus from a Torchwood badfic in 2011, together with her older sister Ruby and her brother Owain. All three were adopted by one of the agents who rescued them. They call her 'Mama'.
While each child shares at least one biological parent with one of the others, none of them share both parents. Seren is the biological daughter of Gwen Cooper and Owen Harper.
In 2014, Seren (at that point, two years old) attended the Purim party. She dressed up as a hamantasch with a sparkly tiara, and was involved in a slime war/food fight together with her brother Owain.
In 2017, five-year-old Seren was visited in the Nursery by Agent Jacques Bonnefoy, who serves as a sort of uncle figure to the three. She was trying her hand at amateur cartography.
In 2025, thirteen-year-old Seren is revealed to have become a Dragon Rider, with ambitions to work in DoSAT. Her dragon (an Eragon-verse rescue) is white, very energetic, and named Ruth. As this is a Ten Years Hence story, it may or may not turn out to be canon.
The mission report detailing Seren's rescue has not yet been released.
