If it means something along the lines of "Only the bold may venture to the stars" than it makes perfect sense if you think about BUNGiE's journey to where they are now. They've been through so much to bring us these great games and they almost burned out a few times. Go on YouTube and watch "O Brave New World" by BUNGiE and you'll understand. it also shows up at the end of the video so... Maybe I'm on to something?
