The issue with the empires is that they act as though they are a power or a true force in the Pirate World when they’re really not. They drop like fleas and call for all their allies, regardless of the size of their enemies. This causes a huge lack of respect for these empires, which in turn becomes hostility.

tl;dr Empires that claim they’re powerful and stronger than any/everyone when they’re not pisses Pirates off.
