Furstyr Rostkammyr Skhyff

Furstyr Rostkammyr Skhyff (FRS/F.R.S) or "Royal/Prince's Rustridgi Ship" (sometimes incorrectly written as "RRS" or "PRS") was the naval prefix formerly used for vessels of the Rostkammyr Maryn, or Rustridgi Navy. Used since the creation of the semi-independant Principality of Rostkamm in 0 K.C, the prefix was applied to all vessels and shore bases used by the Rostkammyr Navy.

Following the dissolution of the principality in 365 K.C and the replacement of the Rostkammyr Navy with the Greyhallow Fleet, the prefix has fallen out of use, with ships of the fleet instead taking up the Stormwindian prefix of "HMS". Some private vessels of Greyhallow and Rustridge will still bear the prefix as a sign of respect for the former Principality or dislike for the Kingdom of Stormwind, although these prefixes have no formal meaning or regulation and are indeed largely disliked by the rulers of the Duchy, being seen as rebellious or treasonous.
