Heroic: it started I think because a huragrok killed a human for threatening Yapyap or Bapap. It ended because of Thel' Vadam killed the prophet of truth. Fun fact: Sergeant Major Avery Johnson was the only human to witness the beginning and the end of the human-covenant war! Legendary: I know one of them was the in Amber clad, I don't know the other two. Can you give me another legendary, no forerunner stuff though.
