10.6  LOST KINGDOMS  When a kingdom is abandoned to bring a new kingdom into play, or when a kingdom is eliminated while still holding territory, all areas owned by that kingdom become neutral (unowned) at the start of the next turn (gains an extra army at the same time).

10.7  HOUSEHOLDS  You may place your household on the map (if it isn't already placed) or move it to any adjacent area by using the KING action. Households may only be placed in or moved to areas that you already own, and may not be placed in a blockaded city. They're not subject to being stuck. Sea movement is allowed (without ships: note that households don't deploy at sea). There is no costs in BPs. See also 3.14 and 6.10.
If a land area containing your household is captured then it is removed from the map (you can put it back again somewhere else as soon as you like) and the kingdom making the capture gets half your treasury (rounded down).
