I rewatched the GDC panel video t'other day, and I suddenly had a thought. Now I know it's unlikely, but what if the fifth, unknown alien race in Destiny (people are throwing "Glimmer" around a fair bit) is actually attempting to ally itself with humanity, having faced the same threat which almost wiped humanity out? What if these pyramid ships we're seeing are the last remaining fleet of "Glimmer" vessels, desperately seeking refuge in the relative safety of the Sol system, what with the presence of the Traveller? While this is just wild speculation and most likely completely wrong, it raises an interesting point - not all aliens are out to get us. Hell, the Traveller is a great example of that. Of course, there's also the chance that the "Glimmer" are the threat which pretty much wiped us out to begin with, were stopped by the Traveller, but are back with a vengeance ready to stomp us into the dust and take our planet for all of its fruity goodness (that's resources to you and I). Thoughts?
