Royal Northian Marines
Her Northian Majesty's Marines or Royal Northian Marines (RNM) are the naval infantry arm of the Royal Northian Navy. The Royal Northian Corps of Engineers were split from the RNM in 1875.
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authority and expense, they were used in the 1600s through the 1800s for a wide range of functions that have now been superseded by the Federal Army and a number of civic authorities. One was to police the Verge of the Palace, a six-mile circle around the royal residence over which the King had direct authority. Another common 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 function led to the monicker His Northian Majesty's Bricklayers, referenced in the 1856 novel Birds of Song, where a Royal Northian Marine was told off by a Federal Army officer, "Get thee hence: thy Bricks wait for thee."
