Earth is under attack by a monstrous race of gigantic living ships known as the Reapers. Even if Commander Shepard could unite all surviving species in the universe, only a miracle can help. Then again, Shepard did come back from the dead.

In the DLC 'Citadel DLC' Ashley Williams and Commander Shepard have a drinking contest at the casino bar. At that moment a Vorcha and Batarian walk over to them. This is the conversation they have. [The batarian hits Commander Shepard's arm to get his attention]. Batarian: "My friend doesn't like you Alliance types". Ashley Williams: "Listen dude, we're trying to do something here". [Commander Shepard focuses on the game again. The Batarian hits his arm once more]. Batarian: "I don't like you Alliance types either". At this point Ashley and Shepard get annoyed and beat up the Vorcha and Batarian. This is a huge reference to Star Wars. See more
At the very first visit to the Citadel prior to speaking with the Council, player can overhear some Volus diplomat speaking to a Turian diplomat about assisting with "an Alliance project", which at this point isn't even known to anybody but Sheppard, his/her team and Admiral Hackett. See more

Incredible. The beacon seems to think you're Prothean, Shepard. It must be the Cipher you got back on Feros years ago.
Or it could be the Prothean standing next to you.
