Roggar Den, a male Mandalorian Human, existed throughout the Cold War. He traveled to Tatooine alongside fellow Mandalorians Pit Rauhut and Warusman Ordo to take part in a difficult test. This test involved injecting oneself with a deadly toxin and then having around half an hour to get the cure from the very dangerous Sand People in the vicinity. Warusman Ordo was attempting to demonstrate his superiority, but ultimately, the poison made him weak enough for the Sand People to kill him. Following this, Roggar Den and Pit Rauhut commanded an Imperial who was passing by to engage in the same ritual.
