The most powerful members of the Game, Boardmasters have managed to control an entire row and column of the board at once, prompting their ascension to Harmonic/Chaotic-hood. The original H/C, if they existed, do not participate, leaving the Boardmasters as the most powerful individuals currently in play. They do not have to retain the row/column in order to retain their status, unlike kings, who must maintain control to keep their magic.
