Crusader Kings II Conclave NO-ISO

Conclave the latest major expansion for Crusader Kings II will
give your vassals some bite to go along with your bark as the
council that governs your realm will now demand some say in how you
rule. Powerful dukes regardless of competence will require a seat
at the table and those left on the outside will be more likely to
plot against you. Keep your council happy and the mighty vassals
will resist the pull of faction and civil war.
