Royal Northian Marines
Her Northian Majesty's Marines or Royal Northian Marines are the naval infantry arm of the Royal Northian Navy.
Name
Because the RNM were originally raised under the King's personal authority and expense, they were used in the 1600s through the 1800s for a wide range of functions that have now been superseded by the Federal Army and a number of administrative authorities. One was to act as a police force in the Verge of the Palace, a six-mile circle around the royal residence over which the King had personal authority, which was often lawless because the RNM were not competent policemen. Another common (and much-derided) use was to erect buildings, on the pretext they were useful for the Navy, for which the Congress of the States refused to pay. This building function led to the monicker His Northian Majesty's Bricklayers that was referenced in the 1856 novel Birds of Song, where a Royal Northian Marine was told off by a Federal Army officer, "Get thee hence, for thy Bricks wait for thee."
