Just posted this on another post but.... Interestingly enough OWL Could also mean Orbital Weapons Lancet.. did a little hunting and found this site (http://www.technovelgy.com/ct/content.asp?Bnum=1583) for an article about it. The really interesting about this site is that it not only talks about Orbital bombardment, but it was also published by "Vangard" in 2007.. and we all know how Bungie loves 7's... does this have any relation... No clue, but interesting enough.... now that I think about it further.. weren't the warminds controlling Orbital weapon system during the collapse? The article mentions that the "Lancets" are "essentially guided steel telephone poles tipped with a chemical warhead. They're designed to fall from low Earth orbit and punch a hole in the ground, through several hundred feet of dirt, reinforced concrete and even steel. They then incinerate anything within the relatively small but very deep impact crater." this could be how the "infection" was spread to the initial guardians to potentially preemptively help out knowing SIVA is about to break out. Maybe Rasputin finally decided to get off his computerized ass and help us out rather then observe from the sidelines and and play music.
