The small council is a body which advises the King of the Seven Kingdoms and institutes policy at his command. It is the inner (thus “small”) council of the King, essentially forming the “government cabinet” of the Seven Kingdoms. Members are appointed to their position by the King; theoretically they can be dismissed at will by the King, however in practice this might lead to undesirable political fallout.
The king serves as the head of the council and takes note of its recommendations, but only the king can make the council’s decisions into law. The Hand of the King is the leading advisor on the council and serves as the king’s proxy when he is not present, in which case the Hand chairs the meeting. If the king is a minor, then by default the appointed Regent will act in place of the king on the council.
The small council meets at the capital city of King’s Landing in the Red Keep, in the same building as the Iron Throne courtroom.
