As at 3061, the Vincent-class corvette Muninn was a WarShip within the Clan Snow Raven touman and was serving as the CSR Muninn, one of five WarShips that made up the Circe Battle Star. Like the other ships of the Circe Battle Star the Muninn was tasked with transporting personnel and materiel belonging to Clan Nova Cat from the Clan Homeworlds to the Inner Sphere at this point in time.
During the Wars of Reaving the Muninn was one of the escort vessels for the last major Snow Raven convoy to leave the Clan Homeworlds for the Outworlds Alliance. Of the fifty Snow Raven JumpShips that had originally been intended to be a part of this last convoy, only twenty-two survived to make it to Quatre Belle in the Outworlds Alliance, escorted by an ad hoc star of damaged vessels which in addition to the Muninn included the Aegis-class heavy cruiser CSR Lord Death, the York-class destroyer CSR Corvidae, the Congress-class frigate CSR Magpie and the Whirlwind-class destroyers CSR Drake and [[CSR William Adams. The Snow Ravens would subsequently blame the losses taken and damage suffered on bandits when talking to their new allies in the Outworlds Alliance.
Having survived the Wars of Reaving and the Jihad, the Muninn was one of the WarShips to be reactivated by the Snow Ravens during the Dark Age. In 3145 the Muninn was a part of the Ice Storm Naval Star; as had been the case in 3079, the Ice Storm Naval Star consisted of the Muninn, the Cameron-class battlecruiser Ice Storm, the Conqueror-class carrier Ark Royal, the Congress-class frigate Magpie and the Whirlwind-class destroyer Drake. As part of the Ice Storm Naval Star in 3145 the Muninn operating from Ramora as part of Alpha Galaxy.
The Muninn is referred to as the Munnin in Wars of Reaving; as Muninn is the name of one of the mythological ravens associated with the Norse god Odin, Muninn has been assumed to be the correct spelling in this article.
