Gunshots echo in Shepard's ears, distant and indistinct. Everything's hazy, clouded over with sleep. Something shakes... whatever she's lying on (it's soft and warm; a bed?), rocking her gently back and forth.
"Wake up, Commander!" Says a woman's voice, vaguely familiar to her; a soprano, from the sound of it, with a thick but cultured English accent. Her mind can't place the precise origin of the accent. That's okay, though, 'cause Shepard's going to ignore it and try to go back to sleep.
Another shake. Shepard blinks blearily a few times. She wants nothing more than to return to sleep.
"Shepard, do you hear me?" The woman demands. Shepard blinks her eyes open, then lets them flutter back closed. "Get out of that bed now! This facility is under attack!" The woman continues. This time, her brain is able to associate a name with the voice, and she knows she's heard it before. Miranda.
Shepard's eyes blink open at the word "Attack". A dull, aching pain is present through her entire body, and the skin on her face feels... odd. Too stretchy in places. She lifts a hand to rub her jaw and is quite alarmed to find little cuts there, not very wide but rather deep.
"Shepard. Your scars aren't healed, but I need you to get moving. This facility is under attack."
More commands from Miranda. Shepard sits up and grasps at her side as pain shoots through it, choking down a scream of pain. She glances around the room, mind taking in details; sterile white, brightly lit... like a surgical theatre? What the Hell am I doing in a surgical theatre?! There's a window in front of her, and her eyes widen as several bullets speed past it. We're under attack!
(The narration would like to note that Shepard isn't precisely coherent at the moment.)
Shepard grits her teeth against the pain and gets to her feet as Miranda informs her, "There's a pistol in the locker on the other side of the room! Hurry!" A burst of adrenalin hits Shepard's system, and she limps over to the locker, finding both the pistol Miranda mentioned and a suit of dark grey armour, the familiar N7 emblem emblazoned in white and red over the breastplate. The pain starts to recede a bit as she gingerly dons the armour, fastening each piece in place with complete assurance. Though it's heavier than the armour she's used to wearing, but after putting on armour every day for more than twelve years, the process is imprinted in her muscle memory.
The pistol is the only gun in the locker; worse, it has no ammunition. Oh, lovely, she thinks, before snapping, "This pistol doesn't have a thermal clip!"
"It's a med-bay. We'll get a clip from—" A hissing sound interrupts Miranda, causing Shepard to snap her head in the direction of the noise. "Dammit! The canisters over by the door are going to explo—"
"Got it!" Shepard interrupts, dashing behind a sturdy glass wall which is currently surrounding a set of crates.
A moment later, there's a bang and a flash of red-orange light. She stands and heads for the door, while Miranda says, "Someone's hacking security trying to kill you. Look for a thermal clip for your pistol."
Not a second after she's through the door, Shepard spots one, beside a downed security mech. "Finally," she growls to herself, picking up the clip and slapping it into the pistol. She feels naked with just one gun; she's used to having a full complement of weapons strapped to her suit, both guns and grenades.
Adrenalin is rushing through her system, erasing all traces of weariness, dulling the pain she's been feeling a little more. Exhilaration floods through her, and she grins broadly as she proceeds forward.
