Ok, so I'm having a little trouble with some stuff that the Books of Sorrow says. In one of the chapters it says that in order for Oryx to kill the mighty empire of people he killed his two sisters and that it was a "true death" due to them being in their throne worlds. It is later said that Xivu Arath (I thinks that how you say it) then materializes out of thin air while Oryx was waging war because Xivu Arath was "war itself" and so she was conjured. It is also said that Oryx tricked a species with cunning arm in doing so summoned Savathûn, because she is cunning itself. If this is true then the Sword Logic has some sort of hole in it due to the sisters being resurrected from a true death which shouldn't happen in sword logic or killing logic. So my question in the end is: Can the Hive I grain themselves into an idea, set of actions, or fabric of the universe for them to escape a true death? If so, have they reached the goal of the Vex in reaching a state of existence that doesn't allow for death or removal?
