  • Terrible Price: To successfully navigate the warp, brave navigators must risk mind and soul by psychically reaching out into the immaterium. In order to rely orders and messages quickly across the vast Imperium, astropath psykers must also expose their minds to warpspace. Both navigators and astropaths are routinely burnt out by their burdens.
  • Thundering Cannons: Armed with massive macrocannon batteries, devastating torpedoes, and lance weaponry, the fighting ships of the Imperial Navy are devastating in space warfare.
  • Great and Small: The Imperial Navy has ships suited to all manner of tasks, from the mighty Battleships and Grand Cruisers down to Frigate and Destroyer-class escort ships.
