The Deathwatch team are sent to a world which has been obscured by warp storms for the past 150 years. The storms still rage, too much far a large ship to remain in orbit, but a thunderhawk could brave entry and land without too much trouble. Last known contact with imperial colonists had reported the place infested with Xenomorphic Kud Bears, and so the Deathwatch are probably the best for the job of recon on this world.
Upon landing the Deathwatch are greated fondly by a race of beautiful humanoids, with small furry ears, sharp claws and dainty tails. The warp has many perils, and locked in a storm of such magnitude for as many years as they were, the colonists were merged with the Kud Bears, and now a new race of human/bears exists.
Loyal to imperial rule, but by all defintions, still mutants and xenos (But by no choice of their own), do the Deathwatch report their findings? An exterminus would be impossible because of the warp storms surrounding the place, do the Deathwatch take on the job of planet wide genocide? Or do they decide that these creatures deserve the right to live and worship the Emperor?
