Necromongers

The Necromonger Empire is a fanatical religious empire whose members zealously and violently follow and propagate its religion Necroism. They are one of the four elder races in the Riddick Universe.

The Necromonger fleet moves from planet to planet, system to system, appearing as a comet before arrival. With their space armada led by the city ship Basilica, they seek to conquer all they come into contact with, and have indeed colonized entire star systems and even purged their races to near extinction. The troops of the empire view death as honorable, and are unable to feel pain. While they do wield guns, it is considered more honorable to use melee weapons.

The Necromongers believe that the Underverse (a constellation of dark, new stars) is their promised land, believing that unless a person dies "in due time" that they will not go to the Underverse.
