So I need a ruling from my dear lovely SE companions.

I have this race of humans, basically it's way back in history and they were the first to build boats and they have come off their island to wage war, rape, pillage and exterminate the other races. I picture then to be hard men, unyielding and total in their need for conquest. The thing I need help with is what I should call them.

Currently I am stuck between The Protocol and The Obligation. Which one sounds better my friends?
