Endurance

Endurance — a Gloriana-class ship, Mortarion’s flagship in the Death Guard’s characteristic livery. It led the legion’s operations at Isstvan III and the Drop Site Massacre on Isstvan V. Notably, for the expedition to the Siege of Terra Mortarion took as his flagship not Endurance but Calas Typhon’s Terminus Est; during the Heresy the ship was under Captain Gremus Kalgaro.
