Slaughter of the Vya

The Slaughter of the Vya was a xenocidal-purge campaign originally carried out by a Host of the Astral Warriors Space Marine Chpater. While engaged with the insectoid xenos race known as the Vya upon the world of Ja'jeki, located adjacent to the Eye of Terror, they were suddenly set upon by the marauding Blood Jaws Renegade Chapter, whose murderous ferocity, decimated the ranks of both the surprised Astral Warriors and the Vya. After slaughtering the remaining xenos, the Blood Jaws focused all their rage upon the young Space Marine Chapter, who were forced to flee for their lives or face their imminent destruction. Even now, the Astral Warriors are ruthlessly pursued by the ferocious Blood Jaws, who are intent on destroying the Chapter and harvesting their gene-seed for their own nefarious purposes.

History
During a xenos extermination campaign on the world of Ja'jeki, the Astral Warriors attacked, and nearly defeated the Nurglich - an insectoid xenos race known as the Vya. During the final battle, the Astral Warriors 4th Host was attacked by the Blood Jaws, whose forces overwhelmed both sides, killing off the remaining Vya and leaving of the 270 Astral Warriors Marines, only 30. The retreating Astral Warriors are still hunted to this day, constantly hounded by the ever pursuing Blood Jaws, who are intent on taking their gene-seed.
