/* Kriegsspiel — the apparatus.
   Two parties in separate rooms, an engraved sheet on a walnut table, and an
   umpire between them with the dice and the tables. The palette is taken from
   the apparatus itself: lacquered walnut, laid paper, engraved sepia, the two
   parties' colours, and brass for everything the umpire touches. */
