After the Sith Lord Darth Vader murdered the one-time Jedi Master Eeth Koth, Koth's newborn daughter was seized by Vader's Imperial Inquisitors. When they got to the Inquisitorius Headquarters on Coruscant, the planet, Vader gave the Zabrak baby to a pair of nursemaids that were nanny droid models. The droids were dressed in red clothing.
The nursemaids debuted in Darth Vader (2017) 19, a canon comic book from 2018 that was penned by Charles Soule and drawn by Giuseppe Camuncoli. Soule referred to them as "the Nursemaids" in his script, though this designation wasn't official.
