The Necromongers are a religious empire that zealously and violently follows and propagates its religion Necroism. An absolutely fanatic group that believes life is antagonistic to the natural state of the universe. They intend to convert or kill all who oppose them.
Necromongers! That's hilariously rad. It's all very poor man's Warhammer 40k.
Hope we can get Star Wars going! Those character sheets are so darned fancy.
