Chapter 826: Ghastorix Gang.

It's all good though. The members of their family fight. That's why they are together. Ghastorix will fight anyone including them if given the chance. They understand him and he understands them. They followed him because they respect him, because they have fun with him, and because he makes them rich. 

Their violent behavior has given their war band a terrifying reputation in the upper realm. They get paid with money as soon as they show up to a place. So they don't have to fight to get resources anymore. It's why they are called a gang since they collect protection fees from others now. That reinforced the willingness of his descendants to stay in the war band.
