The rise of the Malfa Family in Aminya only took place in the recent two or three decades. Although they had been involved in all kinds of underground businesses, they had maintained a good relationship with all the other forces except the Dark Blade. They couldn't help it. Ever since the two forces had their eyes on Aminya's land, the direct clash of their interests made them unable to see eye to eye with each other.
Apart from that, other forces, such as a big shot like the Glittergold Trade Union, or the criminal organization Syer Bandits, would have a good relationship with the Malfa Family.
