Oh, one starts out a prince or a king, all right. That's
before the wedding. That's when she was wooing you.
Once you are in the harem, things are different!
Gradually you're reduced from king or prince to the status of knight, running missions on behalf of the queen. At times you're the rook, the chancellor of the exchequer.
Then, before you know it, you're a pawn, at the mercy of the queen and the little princelings and princesses. You still think you matter. It's an illusion.
You're no longer nobility, my friend.
You're a spent force, an empty suit of armor. It's sad. You, with all of your former glory and strength are that, 'he used to be really something' guy.
You're now fit only to be the dean of the latrine, a mere janitor. You take orders, you don't give them.
You don't remember your days as a swashbuckling conqueror of the world. No, those days are in the mists of the distant past. Your armor? Forget it. You've traded it for hospital gowns, pal.
You leave the ex-castle only to visit doctors, and those visits happen more and more regularly, with more and more specialists, until at some point your occupation is
Professional Patient.
One day they simply put you away, and you don't even know where you are, and if the adult diapers aren't comfy, you don't really notice.
Finally, you just freaking drop dead and that's the end of it.
They stick you in the ground.
The death notice says, "Survived by his wife."
