Warhammer 40k: Minor Xenos

From the introduction: In the grim darkness of the far future, hordes of dark monsters and machines lurk between the stars. Great powers do battle within this twisted galaxy, ruining worlds and civilisations as they war. Between the lumbering Imperium, ruinous Chaos, mercurial Eldar, cold Necrons and the ravening hunger of the Tyranids, many forget that there are a great number of lesser powers among the stars. Xenos that are neglected, but potent in their own ways. Now, Jumper, you find yourself among them.
