I see its possible to edit Famous Kings in default_heroes.txt.

But is there any way to choose or even know when a given King in the list will appear in the game? I notice the first King in the list is the starting King...what about those following? When do the 2nd, 3rd, etc. Kings appear? For instance, is there any way to have King #2 succeed King #1?

I would really appreciate any help. Thanks in advance.
