Added to the Fleet during the last months of 1900, and officially joined the fleet in 1901, this ex-ACM armed collier would extend the range of the Fleet of the Mark much more than the Rohirrim built Tolfalas-class. Also the fact that it is armed like a protected cruiser helped in the protection of Westron shipping during this time of piracy as the ACM fell apart.
