"Go suck yer blade!"
In this scenario - does the player who has the unit in the fortified stronghold still 'govern' the empty villages in that fief, i.e does he take income for those villages.
Secondly - if an enemy moves into one of those empty villages, does this enemy 'control' this village for the purposes of income/tax. Or does the player that already has a unit in the fortified stronghold (but no lords) have 'governance' on this village.
Once a legitimate lord is played by the player who has a unit in the fortified stronghold he can auto-magically reclaim the fief title for that area. I assume he now 'controls' through 'governance' all areas in that fief regardless if enemy units have moved int and occupy there?
Well not exactly: he is GOVERNING them, not CONTROLLING. Check the difference on the rulebook if you feel unsure, section 13.0.
