Council of elders is juridical character of it's own who makes it's decisions through disputes and discussions between it's members. Concurrence there is expected because it is build to function that way. It also does not shape underlying lore nor defines spine of corsair gameplay, but exist as supplementary to what already is by granting flexibility and a dynamic element to corsair faction as a whole.
"And if a corsair is something, he keeps his word - and when you break a corsair's word, you break it for all of us, Honor comes first."
