This is drifting rather close to contemporary IC events that are happening now so I'd like to be careful in what is specifically said, but the Lurian regions retaken now (Vaal/Maf) are those that lurians have insisted are lurian (they were lurian before the invasion) and will be lurian proper again one way or another.
I'd like to explain more, but I think they are events best played out ICly before explanation - so ICly pressure your new king to share diplomatic correspondence if he hasn't already. Luria's position has been quite clear.
