I read the Books of Sorrow, and I have questions for clarification due to recent arguments. In these books they mention separating their deaths, so that when killed they can resurrect. Oryx and his sisters all have this. When Oryx kills his sisters to gain power over his worm, and it says true deaths in the sword world, which world is this exactly? It mentions later that at least 1 sister resides in her throne world, so did he simply kill her physical being? Because she was resurrected later by Oryx when he spoke her name through war. Finally, if an ascendant Hive has their death in a separate world, but they're killed in that world are they dead for good? If not, then Oryx couldn't possibly be dead forever, and then raises the question of are the Hive unbeatable? I really need Bungie on this one, but anyone in the fan base willing to help would be much appreciated too!
