From Conversations with a Friend by Dr. Liara T'Soni
In those chaotic minutes following what we thought had been the failure of Operation: Hammer, all Normandy crewmembers were ordered back to the ship. Several of us objected when it became clear that Commander Shepard had not been extracted from the battlefield, but the area surrounding the Citadel beam had become a plain of slaughter. We had the will to return, but no capacity to do so, and we had injured teammates who needed to be taken back to the ship.
I caught Javik's eye from across a rubble-strewn intersection as we were boarding our wounded into the shuttle. He blinked all four eyes at me slowly and shook his head, just a fraction.
I don't think he could read my pheromones at that distance. I don't think he needed to. I held up a hand, and he stepped back into the shadows. It was my last glimpse of him, the sole survivor of a war fifty thousand years old. He was a soldier to the end, and he obeyed no orders but Shepard's. He could not abandon the battlefield.
In this book I have attempted to faithfully recount all of my conversations with Javik, all that I observed and learned from him, and the profound ways in which he shaped my thinking—about the Protheans, and about ourselves. Although I must assume that the last Prothean has passed out of the galaxy, the mark they left endures in unexpected ways. They shaped us. We carry their legacy within ourselves. And I will always carry Javik's memory, and pass it on, as best I can.
