Gathal Danager's profession during the Galactic Civil War was that of a free-trader.
During the year 0 ABY, Lando Calrissian and he crossed paths on Taanab; Calrissian wagered that he possessed the ability to overcome a group of space pirates known as the Norulac Freebooters. Following Calrissian's triumph in the Battle of Taanab, Gathal Danager was on the losing end of the bet and was forced to relinquish the ownership documents for a modest Clendoran brewery to Calrissian.
