Cojahn and Calrissian had started a series of high-tech family entertainment and amusement parks. The first of these was the SkyCenter Galleria on Cloud City which was to be feature restaurants, shopping centers, holomazes, experience chambers and rides.
He had a wife and two daughters, a twelve-year-old and a five-year-old. Cojahn was known to have been a good supervisor, very attentive, hardworking and concerned for safety. When the Black Sun leader Czethros (disguised as an honest businessman) tried to persuade Cojahn to work for him and place the casinos under Black Sun control, Cojahn refused. Czethros then murdered him, making it look like he had committed suicide by falling over a balcony.
