The Ork Skullhamma led the charge.
Deff Dredds led their little brother Killa Kans into the fray.
The Orks even took to the air in their whirling Deffkoptas.
A sea of boyz advanced before the towering Stompa.
The ramshackle Ork Trukks sped toward the Imperial positions.
The Imperial Battle Line was a parking lot of tanks and men, anchored by a mighty Stormlord superheavy tank.
The Skyshield Landing Pad provided defense for Heavy Weapon Teams as well as the rocket-laden artillery of the Imperial Guard.
A massive and deadly Shadowsword anchored the right flank of the Imperial Guard, its devastating cannon ready to punish Ork vehicles and infantry alike.
The first lines of Imperial defenses: ranks of valiant Guardsmen taking what cover they could in trenches, with a line of Leman Russ variants behind them.
In a vault below Scrap Peak, a different battle raged: the forces of the Inquisition tried to stop the Orks' Prophet from reaching the vortex weapons cache.

The Orks managed to set off the detonation codes, releasing a barrage of vortex weaponry. However, instead of devastating targets all over the planet, the missiles all rained down the exact same spot--right in the center of the battlefield, thanks to the Orks not understanding the aiming of the devices. The waves of successive pockets of reality tore a rend in the fabric of the warp. Worse yet, those "bubbles" of reality seemed to persist: and from them swarmed the servants of Chaos: vile daemons and their Chaos Marine allies who had forseen the event and waited for their release into Sanctus Reach.
The Khorne Bloodletters swarmed out over the Imperial Guard, laying waste to their tanks and men with savage blows from their unholy blades.
The Inquistitor marshaled his forces from out of the vaults below Scrap Peak, hoping that his waves of mechanithralls would stop the Ork assault.
It was then that the forces of the Eldar craftworld of Iyanden joined the fray. They had forseen the warp incursion, and knew that they had use this moment of distraction to strike at the Ork war host--the Imperium was going to be crippled by their dealing with Chaos, which would leave the Orks free to pillage their way across the system (eventually reaching the Craftworld).
The Ork air support, in the form of three Dakkajets, raced across the Imperial lines as the Orks reached their foes. The rattling fire tore up the Imperial positions and left them reeling.
Despite the pressing need to stem the Ork tide, the Eldar were unable to accomplish the task. With the distraction from Chaos and the wave of Orks that came crashing forward, the fragile alliance between Eldar and Imperium was broken, and both forces fled the field. The Orks had won, and the system would burn with their wrath.
