Playable Species/Races in Destiny

Many different species exist in the universe of Destiny, both player-controllable and non-player characters (NPC for short). While it is unknown whether all NPC species are set to be antagonists in the story of Destiny, or whether some will be friendly (IMO this will probably be the case) the army of the 7th column, Bungie, have released some information as to what races are in the game. Although most if not all of the friendly races in Destiny live on the Last City protected by The Traveler, perhaps some will live outside the walls in the last few safe places on the Earth?(If there is any...) Humans, presumably, are the most common race on Earth and in The Last City. Will all of them be friendly? Or could some of them be space bandits? Bungie has described the human species in Destiny as [quote]"relatable, tough, and uncomplicated."[/quote] This race can be played by players. Exo's are a player controlled race described by Bungie as [quote]"sinister, powerful, and tireless."[/quote] Bungie drew inspiration for the design of Exo's from Robots, a tiny bit of Nanosuit from the Crysis series and there legendary Reclaimer himself Master Chief. Nothing more has been said about them as of this post going up. Awoken are a player species described by Bungie as [quote]"exotic, beautiful, and mysterious."[/quote] Nothing more has been confirmed about them at this time. In terms of player design, Bungie drew its inspiration for the Awoken from elves, vampires, ghosts, and angels. Perhaps they could resemble forerunners? "Awoken" just seems like a word that would fit them. We know little about the Vex and nothing more has been said about them at the time of this post going up.
