Orask Wars

The Orask Wars were a series of conflicts centered around the world of Orask in 977.M41. It pitted the forces of the Imperium against a Tyranid splinter-fleet. Though Orask had previously endured Chaos renegade attacks, the Tyranid assault on the world was vicious but disorientated and twisted due to their passage through the Ghoul Stars. The great battle that ensued was brief but bloody, as the Tyranids hurled themselves down onto Orask's defenses which were manned by the Red Talons, Legio Magna, and PDF forces. Despite casualties that mounted into the tens of thousands over mere days, the Tyranids were first pushed back, contained, and finally purged from Orask's blasted surface.^[1]

Evidence persists however that some harbinger organism escaped to the outer systems, and Orask may not have seen the last of the Tyranid horror.^[1]
