The Nevermourn are a warband of Chaos Space Marines devoted to the Chaos God of Longing, Praxia. Afflicted with a daemonic "blessing" constantly bombards their minds with the longing desires of every being in the galaxy, the Nevermourn search the galaxy for these individuals, hoping to recruit them into the service of Praxia. All those who stand in their way are slaughtered in the name of the Lord of the Outcast.
