Bursts of lightning, and the Destroyers achieve orbit over Eden Prime. Six legs tucked underneath them, they sound their great horns in the thin atmosphere surrounding the planet, the five eyes spreading red light against the black metal of their hull. They rise, the soft cricket and low moan of the Reapers marking their passage.
Slaved to the will of Seeker, they turn upon the battlefield beneath their mistress. Plates retract along their bows, fire chambers gathering red light.
And then one explodes. A mass accelerator round the size of a soda can hits one in the side and rips into it, kinetic force and explosive energy tearing a hole in the Destroyer's head and sending it spinning off. The others turn, blaring their horns as the rounds begin slamming against their hulls.
They see the cruisers, the frigates. Miniscule compared to them. Power less than what they, even lesser to the Greater Reapers, can bring to bear. Engines flaring and guns pointed towards the Reapers, they approach the planet from the Relay. Bits of metal glance off the kinetic barriers of the destroyers, falling into the atmosphere and burning up.
And then they see the ship behind them, just as another round arcs around the planet and smashes one in the face.
On the bridge of her dreadnought, the red haired captain tents her hands in front of her face and grins.
"SSV Normandy," Hannah Shepard says, "This is the Fifth Fleet. We are here to lend assistance."
A hand comes down on the back of her chair. She glances to the side and nods to the white haired man standing next to her. "Eden Prime Militia," he says, "This is Admiral Hackett. Put me in touch with your commanding officer."
Between her chair and the half circle of sensor stations, a blue image appears. It resolves into a young woman in combat armor, saluting them both and holding a rifle in her free hand. "Admiral Hackett, Captain Shepard. Emily Wong, acting Lieutenant. The CO is currently indisposed."
Hannah cocks an eyebrow. Hackett folds his hands behind him. "Indisposed, Lieutenant?"
"Sending you the satellite feeds now." The girl disappears, and becomes a screen, just in time to for them to see the flash of light as a walking tank is torn in two by a six armed man. No, no. Not man. A man doesn't have those many eyes. Slowly, deliberately, the alien turns as it hears the beeping, the screen resolving into an image of his giant head.
"I am Javik. Avatar of Vengeance of the Prothean Empire and Chosen of the Sun. Identify yourselves."
