The beam of molten metal carves into the side of a cruiser, its guns going silent as the Normandy waves around the soon-to-be wreck. Cannons drop from the underside of the swept back ship, twin beams of blue light lancing out and crackling against Harbinger's shields. The Reaper turns to the Normandy as it banks, a blast from between its tentacles missing it narrowly enough to send the barriers rippling and shaking the ship.
Cursing, Joker dances his fingers over the controls. "I swear that thing is really starting to tick me off. First it sends a big old flying rocky dick to blow up the old Normandy and now he's taking potshots at the new one!"
In the seat next to him, eyes glued onto the displays, Kelly gives no retort. Instead, her fingers work with purpose. She redirects heat bleed off, reinforces the kinetic barriers. "Ken! Gabby!" she yells, "Redirect power from the main cannons to the barriers! We need extra power to the verniers while you're at it!"
Another blast misses the ship as it dips and dives, blasting past the fleet and carving into a passing comet. As the Fifth Fleet- dozens of frigates, tens of cruisers- hammer upon the massive dreadnought, Harbinger does not care. It only focuses upon the frigate. Upon Shepard's ship.
The dreadnought moves, past the crippled Orizaba, past the ineffectually firing fleet. Sweeping its tentacles back, Resplendant Harbinger of Ascension accelerates. It moves faster than something its bulk, its size should. A steady red glow builds up upon its seamless black surface, and the red beam lances out, cutting across space and distance in a sweeping motion.
The Normandy curves, sways, rolling around the beam before it cuts out. A second blast, and it rolls, dives and finds the dreadnought turning in time to follow even as an entire fleet fires in pursuit.
"I am getting pissed off at this guy!" Joker yells, grinding his teeth, "EDI, do we have a location yet?!"
A screen folds out, quickly resolving into a map of the immediate area. Dozens of blue triangles, one large red triangle, and finally centering on one in particular. It zooms in, clarifies, and becomes a hologram of the disabled, spinning Iri.
"Thank you!" His hands move, almost a blur. Swinging around, forward momentum carrying it as it turns, the engines flash and the Normandy takes off. Directly towards Harbinger.
Joker goes quiet. Kelly blinks, stares at the incoming dreadnought, and clenches her eyes shut. Behind them, in the CiC itself, everyone holds onto something sturdy or bolted down.
"Okay girl," Joker breathes, "Just like we planned. Kids?"
The consoles glow blue. One by one, controls lock out, systems activate, all save for the console his hands hover over. Deep within the Normandy itself, the engine, the glowing sphere at the heart of the ship ripples and flashes. In Engineering itself, the two specialists take a careful step back as the controls and computers flash and sing.
Harbinger continues on its course. A single red eye focuses upon the ship, and the red beam lances out. The Normandy continues straight on, a single white and black arrow against the unstoppable. It does not dodge, it does not weave. It does not have to.
Instead, as the beam crosses the distance, the barriers around the ship shift, moving. What should be a single bubble becomes something else, rippling and wrapping bands around the starship. They move in time, independently, faster than any computer could calculate. Faster than any system could handle.
Instead, it begins working. Liquid metal accelerated to percentages of lightspeed is caught in waves of gravity and slapped aside. Inch by inch, piece by piece, the unstoppable crimson beam is stopped. It is disassembled, frozen, and discarded.
Flying through the dispersing cloud of black metal, the Normandy accelerates. Past the beams, it dips beneath Harbinger, speeding past the dreadnought as it struggles to turn, struggles to understand what just happened. The bass roar that vibrates the floor plates beneath Joker's feet sounds enraged more than anything. And that just makes Joker smile.
"Give the kids a cookie, EDI!"
The blue sphere pops out next to Joker's seat, surrounded by several smaller orbs. "AIs do not respond to treats the same as organics do. But I believe they know their act was appreciated, Jeff."
The Normandy speeds past the fleet, weaving between stray cannonfire and debris, towards the disabled Orizaba and the mass of expanding metal. It dives, barriers flashing as it wades in, and comes up next to the floating, spinning giant spider.
There is a pulse of the barriers, surrounding the disabled EDI, and it is gently shoved back towards the dreadnought.
"Iri's on her way back to the Orizaba," Joker says, "EDI, has Harbinger stopped shitting itself in rage yet?"
There is a flash of motion. Harbinger appears before them, tentacles extended. Eight points of light on eight extended tentacles. Despite the fearsomeness, despite the massive size of the warship focused entirely on the Normandy, Joker only allows himself a brief, knowing smirk. And behind Joker, on the ramp leading to the galaxy map, Jacob Taylor allows himself is best shit eating grin as the tactical map fills with blue triangles.
"Message received," EDI states, "It reads, 'The Geth hearby declare hostilities against the Old Machines.'"
And the Utopia Relay erupts as dozens, hundreds of Geth ships jump in, and immediately open fire on Harbinger.
