I think I get what Ryu is asking. The Manse itself was once a military base dedicated to serving the Deliberative. However after the fall of the Solars over thousands years prior to the start of the game's setting things had to change. As time wore on the old structure of doing things simply could not be maintained. It had to change as well new people were born on the island were not assigned their by the military of the Deliberative and such. Therefore it's kind of developed into a sort of pseudo-quasi City-State all it's own with a mingling of civilian and military operations going on. Right now the current of the Lord of the State as we'll call it is the Solar Umari.
