TK-27342, otherwise known as Deena Lorn, was a stormtrooper serving the Galactic Empire, and was a human of the female sex.
The character Deena Lorn originated in "The Witness," a short story penned by Adam Christopher. This story appeared in the anthology From a Certain Point of View: The Empire Strikes Back, released in 2020. Lorn's stormtrooper identification was conceived by Christopher as an homage to Bria LaVorgna, a writer who uses TK-27342 as her identifier within the 501st Legion fan group.
