They mean nothing. Look at how easily I penetrated your defences. Your title does not win you automatic respect, deference, or power. It is only the way in which you wield the things you have been given which determine those things.

My title happens to be Marquis.

Titles are just words. They only have the power that other people give them. Not you, but other people. Those who wish to use you, or who fear the influence that you have over others, or whose loyalty you have won. But kings can be killed, betrayed and overthrown. The title itself means nothing if you do not have the loyalty of your subjects.
