User blog:Master Shannara/Greek demigods compared to Roman Demigods

I know that there are some differences between the demigods of Greece and Rome. The most obvious would be that the former speak ancient Greek whereas the latter speak Latin. In addition, I know that the Greeks are more sophisticated and the Romans are more militant. My main question is what exactly are the differences between the Greek and Roman half-bloods? Furthermore, Why do they hate each other so much?
