As we know, oryx has two siblings that are out and about as well as possibly Taox (the hive that murdered his father). They also never mention and end that comes to Quria (the vex God created after Crota wounded himself with the help of his sisters). In a couple of missions it also mention that's the head of the Cabal empire has been sent a transmission notifying them that their legions have been all but obliterated. There is also the question about the ahamkara because although the grimoire card states they are extinct, it also need with "oh reader mine" which sounds a lot like the ahamkara's speech. So.... Input guys?
