If you properly conduct yourself I don't see why you wouldn't continue holding the 'possessions'. Honestly this isn't like WiR where there are rolls and such, many of the actions involving colonies and rebels are up to the player. This is more of a world-building/story-telling NRP with diplomacy and military command added in, so it's all up to you.
Oh wow I didn't expect anyone to ever post on this again. Yeah this is still alive if everyone is still up for it! Also yes Albania and Moxalt are totally up for grabs so no worries on that!
