Also, can back up my theory that Oryx is Vex, and so is the Hive. But they are neither. Those names are of the two created from the split of one. I'm thinking of calling them the Priores (Latin for the Ancients). The shard Crota was contained in is the same material that the Black heart is, except the Black heart is more alive, and Crota's soul has been dormant. That is how they preseve their genrals. Pus, the Vex and HIve armor are the same metal, just the Vex fresh produce them.
