Perhaps it doesn't make sense to move a realm at all.
My Character i'd consider a Madinan, grown up in the original Madina (not the half baked monarchy that calls itself Madina now, Ulfgang
), will always take Madina with her where ever she goes.
Any place she goes to will be introduced with a little bit of seafaring, liberal pirate like Madina.
Which will motivate her to do certain things, or form certain opinions.
This will in turn influence her actions and which ever realm she is apart of.
The values, the people and the ideas of a realm can be moved, but moving the realm it self is perhaps not even theoretically possible.
Moving the country Russia into the USA for example could be done, but that still woudn't be the same Russia.
Even if the white house would be knocked down and replaced by an exact copy of the Kremlin, and all the Americans where moved as well, it still wouldn't be Russia.
Sure after generations or so of propaganda and or guns put against peoples heads, people could start calling the USA Russia, but that would be the same as forcing people to call cats dogs instead of cats.
Its definitely interesting to see what it WOULD be, but it wouldn't be Russia.
If we agree that realms can and should be destroyed then i agree with Zakky that it would proabably benefit gameplay to keep the realms close together, kill off the few which are furthest away from each other.
If we don't want to destroy realms but do want to reduce the size of them, we should hit all realms equally (with rogues) in order to remove about the same percentage of regions per realm.
Another point which i haven't really heard thill now is that perhaps changing or influencing anything in the game is doomed to fail or create negative effects and also create an expirience of injustice amongst players.
Perhaps it was wrong in the first place to change something.
If realms don't have enough nobles, let it be and let it either destroy its self by the hands of players, or not.
Eventually people could leave boring realms, or be destroyed by more crowded other realms.
Perhaps its best to leave everything up to the players and stop interfering with their game by adding or changing the rogues.
Remove the whole mechanism currently in place that increase rogues when noble region ratios are low.
The Adam Smith or the natural evolution way.
Looking back i think i would have personally preferred that.
