This came up in one of Hosh And Tosh's "what would you do?" Posts It has been confirmed that there is still a 5th unknown enemy. We know that there are the Fallen, Cabal, hive, and Vex but have no info one the 5th. This interests me greatly. Is the 5th enemy the key to the huge puzzle of this story? Are they somehow connected to the traveler? Of you have any thoughts, speculations, ANSWERS???? On this subject post below
