We thought ourselves powerful, able to conquer a galaxy with nothing but toys.

Wrong Place, Right Time: A Hero's Story by DLTA-BOT reviews
The journey of a hero doesn't always start where they expect. It doesn't always happen to those who expect it. Damon was never interested in being what SPARTANs represent: an implacable force for good standing as humanity's shield. Like most other third-generation SPARTANs, the war took everything from him. All he wanted was to return the favor. Sometimes we don't get a choice.
