Theories

(This is a repost of my original Hive Theory) The Theory Before we fought Crota in The Dark Below, we faced his invasive lieutenants on the surface, namely his Eyes, Hand, Fist, Will, Might and Soul (there may be more I haven't mentioned, but the point I will make is the same). We also face the Swarm Princes, abeit in the vanilla game, who are basically his children. This is one theory; the power of the Hive "Gods" is determined by their followers' worship. Notice how Crota never "died" on the Moon? When he first invaded nothing killed him, yet he became ethereal. This coincides with the construction of the Hellmouth. This, for me, has a shocking truth; the Hive "Gods" are not real, they are worshipped into existence by the Hallowed Hive. Notice how the Hive are constantly praying, begging the Darkness to bring these horrors to life. The leaders of that Swarm name themselves for a certain God and ask the Darkness to create him. Crota disappeared when he took the Moon, why? For me, the answer is that he was taken back by the Darkness. The Hive then bargained with the Dark, to destroy Earth and it's light, to see their champion again. This is basically the Darkness manipulating the Hive into exterminating the Light for the price of seeing one of their Gods in the flesh. Shockingly, this shows that the Darkness is able to create Gods and does so to manipulate races. The Vex cannot understand the Heart of Darkness in the Black Garden, so they chose to worship and obey it. The Hive obey the Darkness because it can show them divinity of their design. The Cabal are invaders but are hinted to be running from something, maybe this is the Darkness pushing them to destroy the Light and the Fallen are scavengers with a reverence for anything they can't steal from. This explains Crota, the Heart of the Black Garden, and possibly the Traveller, as being manifestations of Darkness and Light, warring against one another for a reason. Could the Traveller be manipulating Humanity into fighting the Darkness with the promise of another Golden Age, our primary reason for it's defence?
