He tries to start a massive revolution and replace the NPC monarchies with a democracy of the pawns on both sides, sees his revolutioniaries get single-handedly murdered by an all powerful NPC boss the rather dim kids created by accident, and then goes through a bunch of other adventures including literally having his stomach ripped out and generally going slightly mad, spending hundreds of years alone designing perfect civil societies out of empty cans, and being treated like a slightly cute pet by the main characters (despite the fact that the first main character would have been turned to mush at low level if the Mayor hadn't helped). Anyway, the good news is that after this career of incredible badassery, the Mayor and one of his allies manage to achieve his ultimate goal and throw the two royal rings into a volcano (definitely not cribbed from anywhere, that idea), thus allowing for the new post-game world to be started without a monarchy and for him to have a happy ending actually seeing his plans for a better world come to fruition.
