User blog comment:Master Shannara/Greek demigods compared to Roman Demigods/@comment-4424744-20111009090056

The Greeks were the people who caused the fall of Troy, Aeneas was a price of Troy and later traveled to Italy where he became the start of the Roman bloodline. I think they would hold a grudge for that. The Romans invaded Greece later on as well, and made it part of their empire. After the Holy Roman Empire collapsed the eastern (Greek) half, Byzantium, survived as mentioned in the Son of Neptune. Both sides disliked the other and never got round to forgiving each other. The Demigod Civil War that was mentioned shows that much.
