"Abstergo Entertainment is already well known for huge advances in technology." Professor Simon Hathaway says, standing on a stage with the 'Abstergo' logo behind him. "The Animus. The ability to view memories in three dimensions. Reliving the past. But what if…" He pauses, allowing a tension to form. "...we could do more? That's exactly what we've done. The previous iterations of the Animus went to the past using memories and genetic coding. Using a similar concept, along with some scientific predictions, we have done more. Introducing...The Animus Quantum. Where previous devices allowed going to the past, this one...can show the future. A massive step forward for Abstergo Entertainment, Abstergo Industries, and the scientific community as a whole. Which rings true of our motto: "We change the world every day, in a hundred different ways."

The year 2186

The Citadel

A flash of black and red slips through the crowd of panicked civilians. Gunfire and explosions ring out across the normally peaceful Presidium as men in white and yellow armor march in, wiping out any resistance. Reaching the railing, the figure looks down at the chaos below. Several levels down at a dizzying height, a group of Citadel Security officers are engaged in a firefight against a massive squad of soldiers. Among them is one moving in a different direction, towards the elevators to the Embassies. The figure pulls on a pointed hood and quickly descends the identical Presidium levels with spider-like reflexes. She takes position over a hulking soldier who looks like the leader and lets go of the railing, hidden blades extended. She lands feet first onto the unsuspecting Centurion's shoulders and pulls him down, slipping in a quick stab under his helmet, slitting his throat. Several Troopers nearby jump in surprise, and the Assassin uses it to her advantage. Two of them train their sights on her. She grabs a third and stabs him through the shoulder with one of her blades, pulling him in to take the shots.

The falling bloodied Trooper reveals two confused ones with now overheated weapons. The Assassin dives between them and pulls the legs out from under one of them. In a panic, he grabs his buddy as he falls, pulling them both down. The Assassin quickly pivots and subdues the both of them. By now, the rest of the Troopers and Guardians have taken notice.

A Trooper raises his rifle to fire, but the Assassin kicks his legs out from under him. At the same time, a second swings his rifle's omni blade at the Assassin's head. She parrys the swing, taking hold of the Trooper and spinning him around so they are back to back. The Assassin pulls the second Trooper up and over her head, dropping him on the first. She rips the rifle from his grasp and stabs the blade through both of them. The Guardian approaches next, but before he can act, the Assassin kicks his shield into him, stabbing a blade through the slot into his face. The last Trooper raises a shock dagger and starts to swing. The Assassin's blade connects with the armor on his forearm. Her other blade comes in and stabs him in the side. In surprise and pain, the Trooper drops his dagger, and the Assassin plunges the blade into his now exposed neck. As he falls, she takes notice of the surviving security officers, who stand in awe at what the just witnessed. Before any of them can say a word, the Assassin quickly vanishes.
