The most badass human to ever live. Led the war against the forerunners in the human-forerunner war. Had we not been simultaneously fighting off the Flood, we probably would have won. That's right, HUMANITY AT THAT TIME WERE ADVANCED ENOUGH TO NOT ONLY HOLD THEIR OWN AGAINST THE FREAKING FORERUNNERS, BUT ACTUALLY BEAT THEM. Once the Forerunners beat us (we had no more resources left due to the war with the Flood) they devolved us back to prehistoric technology as well as form (pre-homo sapiens) and destroyed all evidence of our technology and fossils which is why humans never found out about our real origin and history. Only what the forerunners left us to discover in the form of fossils.
