This piece of information represents Those who came before. Three lives lost- The people who we see in the vaults are just holograms, they are not the actual person.

The Greeting- This represents Minerva, as she greeted Ezio and explained everything that is going on (as a greeter would).

The warning- This represents Juno. Search  Juno wiki and click the mythology link. Then click Juno Moneta and part on that say she warns.

The revelation- maybe represents Jupiter or Eris. Probably gunna be revealed in AC Revelations.
