Hammer of Mawds
Recruit

I personally think it be a fine addition being able to build a spy den in your castles and towns, they would get sent out to enemy locations giving you info on when an attack is about to happen at one of your fiefs, let's say a 7 day advance warning that gives u enough time to try and prepare for it.
Also if you can't make it you get the chance to play as your governor in that castle or town that needs defending would be a good option.
