I'm pretty sure that Guardians don't actually die unless they are kill by the "darkness" or something. They are invincible, magic, wielding dudes. I like the Halo universe more but Guardians would win.[spoiler]Edit: People have been replying with some cool lore from Destiny. If only the story in the game was a little darker and had some of this cool, twisted lore involved the story would be way better.[/spoiler]
