Pirtonna's occupation was as an enforcer. He was employed by the Birtraub Brothers Storage and Reclamation Center located on Crovna. This occurred in 0.5 ABY, the era when the Galactic Empire was at the peak of its power.
The discovery of Mara Jade's arrival at the Reclamation Center was made by Pirtonna. Jade was there to investigate Moff Glovstoak. Pirtonna then accompanied Jade to the office of his superior. He then attempted to intimidate her by drawing his blaster. However, Mara had no patience for such unskilled methods and swiftly disarmed Birtraub before any harm could be inflicted.
