First, I would just like to say that user [b]Insomniatron[/b] suggested the idea on another thread. I'm simply stating the idea. There are a few grimoire cards throughout the library that talk about fallen. One in particular speaks of a Fallen Vandal that Cayde-6 encounters that actually helps him fight several Hive. This is, to say the least, badass. The queen also has two bodyguards in the story ( I've seen the cutscenes 9001 times so I remember that). This may suggest that the Fallen (lower ranks at least) are merely slaves serving a master. If the slaves could be freed, than maybe they would help us against the darkness. So how about a 4th playable race. Instead of calling them the fallen, however, they could be called [b]The Risen[/b]. Several cosmetic factors could also be added in i.e.: different breathing apparatuses to assist in ether intake( these would replace the hair options)different scars, and several eye colors. Docked arms and non docked arms may also be an option, along with tattoos that show their old loyalty to a fallen house (Devils, Winters, etc.). The story would be pretty simple. You are a Fallen that was woken from death by the traveller, just like the other gaurdians. Along with this tree, maybe their could be a fourth class released. I have no ideas on this, but in most games that Destiny takes it's roots from, races and classes are released hand in hand. Comment what you think!
