A literal read of the information released today suggests that [i]it[/i] (the Traveler) was responsible for terraforming two planets of its own accord. (Until now, I think a lot of the community has believed that technology derived [i]from[/i] the Traveler was responsible for the terraforming.) It was also being chased by a significantly-powerful enemy that penned it into a corner and wiped out most of the human race in the process - almost as if we were collateral damage. Under the circumstances, I'm not sure I want to know how it defended itself. It's like playing with fire.
