Hmmm...
What is the difference between the Cagilan Empire and the Zuma?
Or Sirion. Or Enweil (pre-fourth, most likely). Or any other powerful realm?
Powerful realms have their own goals and they will !@#$ you up if you stand in the way of them. This is not new or unique to the Zuma, so why is there a twenty seven page thread about why it is the epitome of evil for the Zuma to do so? Hell, the Zuma have had less impact than a realm of equivalent position (SA...) would have had because of how passive they are.
