Warden Eternal (Emergence)

"were chosen. The Mantle of Responsibility was to be passed to you. You were to maintain an everlasting peace within the galaxy, to tend to and protect the lesser species who would depend on your care. And now...look around you, Spartan Locke. Your kind has committed countless atrocities in the name of its own arrogance. Genocide, oppression, murder of your own children! It seems on one matter, the Forerunners were correct. Humanity must never be allowed to hold the Mantle for themselves. Not one of the species in the galaxy today is worthy of guardianship...on the contrary, your behaviour confirms that guardianship still must be imposed on you."
