Star Kingdom of Manticore
The Star Kingdom of Manticore (abbrev: SKM) is a fictitious interstellar nation featured in David Weber's Honorverse series of books.
During the events of the series, the territory subject to the Manticoran crown expands and the SKM becomes the nucleus of the Star Empire of Manticore (SEM).
During the time period of the Honor Harrington series, the sovereign of the Star Kingdom was Queen Elizabeth III, of the Winton dynasty that had ruled since the kingdom's founding.
As the Royal Manticoran Navy is the Senior Service of the SKM, most members of The Royal Manticoran Navy: The Official Honor Harrington Fan Association, Inc. (TRMN) portray Manticoran subjects, although they may also chose to roleplay as Grayson, Andermani, or Havenite personae.
Although the kingdom and its ruler are fictional, TRMN formal documents such as officers' commissions and patents of nobility are in the name of Her Majesty the Queen, which lends them in-universe flavor. The leadership of TRMN in the form of the Royal Council led by the First Lord of the Admiralty run the organization in the Queen's name.
At TRMN gatherings and dinners it is customary to give the Loyal Toast:
Proposer: "My Lords, Ladies and gentlemen, please rise for the Loyal Toast. I give you...The Queen!"
Response: "The Queen!"
