Logic doesn't apply to M&B feudalism. A noble just married his highborn daughter to a man who grew up as a street urchin, a man who would never ever be made a noble here on earth just because he commanded a modest mercenary company and killed some local bandits.It's actually kind of logical you know. Lords will not support anyone who does not have atleast some claim to a kingdom. The player character starts out independent and has not claim to any kingdom. So the only way to become a king, is to start a new kingdom.
AFAIK, it's always been implied in M&B 'lore' that the player character will unite Calradia and restore the long forgotten empire.
