In a world where robots have complete minds and humans have bodies as strong as robots, any intelligent being can always casually tell a story or two about Commander Shepard.
The file on your desk is provided by a library in Orion that is being auctioned. It records some historical facts that happened after this legendary figure ended the Reaper war and before he went to Andromeda. This dossier was once listed for sale on the library's online store for seven credits. After being ignored for five years, the library went bankrupt. It was photographed by you, bundled with a pile of Asari clothing magazines, and quantum teleported to your desk.
You could tell a lot about Commander Shepard's story, but it seems like you haven't read this one yet. Although you weren't particularly interested, you didn't have enough time to play games on the way the spaceship landed in the Leo Nebula, and you were too bored to sleep, so you yawned and turned to the first page.
