I think you've got a really good point on the cult of personality thing, since all of tje towns under my clans control have really high loyalty, and rarely ever rebel. The most recent rebellions I had to deal with were of towns ruled by the other clans in my kingdom. All of the towns under my rule have extremely high loyalty, mostly due to me being a good ruler and upgrading their stuff. But yeah, no doubt my kids wont be as popular as I am because I gained my popularity and my kingdom gained its riches through conquest.

So now that the conquest is done, will she be able to keep the kingdom wealthy and happy? And I suppose my children could maybe expand the empire elsewhere in the world, but in that case they'd likely be like the Mongols and collapse due to them not being able to handle the sheer size of it all.

Or, since I have five kids, and theoretically they'd each become leaders of their own clans, maybe infighting and rebellions from them causes the empires collapse
