The Privy Council was a group of advisors to the High Lord (or High Lady) of Tapani sector Noble Houses. The council was typically drawn from the highest status nobles within each house. This comprised about ten percent of the noble class of which most were Lords.
The role of the Privy council within each house varied. In some houses the council was an advisory body only with no direct power. In others it is the power behind a figurehead High Lord. Typically a High Lord had a fair amount of authority to formulate public policy but since the privy council represented the most powerful families the High Lord normally took their advice under consideration.
