Every 5,000 years, the accursed world of Acheron emerges from the warp. Drawn by its legend, three factions – Space Marines, eldar and orks – battle each other to possess the great weapon that is said to reside there. But when the weapon is finally revealed, a terrible threat rears its head. Can the three warring generals do whatever it takes to put aside their differences and defeat the ultimate evil? Set in Games Workshop's Warhammer 40,000 universe, this novelisation features characters and events from Dawn of War III, the third game in Sega and Relic Entertainment's phenomenally successful RTS franchise.
