Jasko was a male who studied at the Arkanis Academy on the world of Arkanis. Being a cadet there, Jasko was on track to potentially become an officer within the Imperial Military. Nevertheless, Jasko failed to complete his studies. He felt animosity towards the academy's supervisor, Commandant Brendol Hux. To irritate him, he established an establishment called "Jasko's" in Scaparus Port, a small spaceport town merely a few kilometers away from the academy. At this location, he offered private, unmonitored comm station access for a high fee and was also reputed to be the only one in the port capable of brewing a palatable cup of caf.
