These questions have no visible answers and the Lord behind the actions has refused to comment on what he might be planning.
For weeks talk has spread of the possibility of war, talk which most had passed off as idle threats and chatter. But now a force has been fully mobilized and based on the principals which drive military action it will by no means be the last.
The majority of the issues which are currently creating friction between the Tokian lords are the direct result of King Bayen's "New deal" which requires citizens to recognize their lord for the lord to continue holding his title. Normally this wouldn't be a problem except that the current population of each realm by no means reaches the population needed for all 5 Lords to remain in power. The possibility that they might lose the positions they have worked hard to gain is highly troubling and has been driving them to drastic measures.
North's reasoning for this massive build up can not be clearly understood but given the current fragile state of the nation this action might be the one which shatters the peace and sends the nation into chaos.
