A stormtrooper from the Galactic Empire, who was a male human, authored The Official Stormtrooper Training Manual, which is a training guide for stormtrooper cadets. The writing of the book by this stormtrooper occurred sometime between 4 ABY and 5 ABY, and it detailed the significance of the Stormtrooper Corps. During the author's writing process, he accidentally collided with a wall and humorously asked that the reader refrain from reporting the incident to Darth Vader.
