Foundling
From Tardis Wiki, the free Doctor Who reference
The Spy Master identified the Timeless Child, who had been adopted by the first Tecteun, as a foundling. As the second Tecteun had the child's ability to regenerate gene spliced into the Time Lords, the Master observed that "the foundling had become the founder". (TV: The Timeless Child [+]Loading...["The Timeless Child (TV story)"])
