Gryxxink was leading some clone troopers through a jungle when Order 66 was issued. Just before they opened fire, a separatist unit launched an artillery attack. General "Shink" threw a Force Umbrella over them and they dug under. They continued forward after the initial launch and pursued the opposing forces. This was not a droid unit but one of the few sentient groups that have rebelled against the Republic. Lt. Kick was in a bind. He was compelled to execute his commanding officer but his sense of duty and loyalty to Gen. Shink overrode the command. Not only the Lt. but the entire platoon. They got on their short range comm system and discussed it while pursuing the enemy. In the end, they warned the General and allowed him to escape. Upon returning to the regiment, Lt. Kick told the commander that General Shink had taken a mortal wound and vanished as he became one with the Force. All they had for proof were the general's clothes and Jedi robe. Lt. Kick suggested that they shoot a hole approximately where Shink's hearts would be and soaked it with some of the general's blood.
Five months later, Shink was able to reunite with his pod brothers, Zee and Q, also Jedi. The three wandered the galaxy as a freighter crew aboard different ships as work came their way. They did what they could for those in need but kept as low a profile as possible. Even during most of the Civil War, the brothers did not reveal their identity. Eventually, they owned a ship of their own and smuggled for the Rebellion. After the destruction of the Second Deathstar did they introduce themselves to Luke Skywalker and the Alliance leaders. It was decided that the three would continue their smuggling and aiding those in need. In addition, they would take on missions for the Alliance.
