Piperii-Cerlurn's primary business was the creation of weaponry. A significant product of theirs were the R-90C medium blasters; these were installed on both flanks of the control module found in every Imperial AT-AT walker.
The concept for Piperii-Cerlurn originated with Michael Kogge. He devised it for the Star Wars: Rogue One: AT-ACT Deluxe Book and 3D Wood Model activity book released in 2017.
