Two problems: The traveler helped us before we were struck down and if something that powerful struck us down wouldn't the be nothing left but dust of the cities on the other planets? [quote]Everything changed with the arrival of the Traveler. Long ago, it breathed new life into our system and began our Golden Age. But it did not last. Something hit us. Knocked us down. [/quote] *Edit* Then again they could of captured it then used its power to breath life into the solar system but that wouldn't explain the name "Traveler."
