Atheon. His health is amazing, he would never die since nothing would do the damage to kill him without Times Vengeance. Or Crota.. he doesn't die except by the Sword of Crota. So, therefore.. Darkness wins. And they would likely come out in an all out war. Because it's an all out war. And gorgons would also come out in an all out war.. because of an ALL OUT war. Means everything against everything.
