Article 154 - King
Canon 6612 (link)
A King is a 13th Century word defining a male monarch, the member of a royal family who is the supreme ruler of his nation.
Canon 6614 (link)
The word King was deliberately founded as part of the formation of the Art and Game of Chess from 1223 CE. Therefore, in an occult sense, a King is literally a piece on a chessboard.
