Crota (And Possibly the Hive) Once Guardians?

Hello fellow Guardians! I'd like to thank you for participating in the Killworthy Gaming community, and helping us figure out the hidden secrets of Destiny. This is my first post here, and I hope you'll enjoy. So as we all know, "The Dark Below" DLC is coming out tomorrow. I personally can't wait for it, as it regards my theory. So we all know a bit about that overload Hive leader, Crota. But do we really know his origins? I've been researching a whole lot about this guy for quite a bit, and I believe I've struck gold with my theory. Before I start though I would like to apologize if you also thought up this theory or it already existed before this post. But here we go. So this first piece of evidence is the main reason to why I believe Crota, and maybe even the rest (or most) of the Hive were once Guardians. In the Grimoire card "Ghost Fragment: Warlock 2", Eriana-3, a Praxic Warlock, interrogates a Hive Wizard, and what she finds out in the Wizard's mind is pure gold for this theory. She says in this card, [i]"It showed me the battle. It showed me Wei Ning dead on Crota's blade. It showed me how Crota killed a Guardian with a screaming knife hammered out of his own [b][u]Ghost[/u][/b]."[/i] Wait a second. Ghost? Ghosts are only used by Guardians, and each Guardian owns his/her own Ghost. They aren't available for purchase by anyone either, and especially not for the Hive and rest of the Darkness. So I, myself can strongly believe that Crota was once in fact a Guardian. Another interesting detail is that before Eriana figures this out about Crota, she states, [i]"It responds to the Light. Hurt it again."[/i] This stands as an ambiguity, or double meaning, meaning that the Hive Wizard not only dislikes the Light as a Darkness, but also responds and maybe even listens to it. So does this mean that the Hive Wizard, just like Crota, may have been a Guardian once before? We really don't know yet, but how did Crota and the Hive Wizard really come to be what they are now (Hive)? The official cinematic trailer for "The Dark Below" DLC sheds us more light on why they may have came to be what they are now. Although we do have some more key parts of this Grimoire card still left to cover. Eriana also states in her story that, [i]"It (the Hive Wizard) laughed at me. It said we were the same."[/i] Does this mean that the Hive Wizard was once a Guardian just like Eriana also? This only adds to the belief that most of the Hive were once Guardians also. But here we have our final quote from this card, where Eriana says, [i]"Kill the Wizard. Scatter the ash. It has nothing but lies to offer."[/i] From this bit our theory gets a little scrambled, as this could mean everything we learned from the Hive Wizard is false. But this could just have been something Eriana said as an instinct due to her fear and/or misbelief of what the Wizard told her (which was really true in reality). Anyways onto the official trailer. [url=http://youtu.be/nk1p34lAol8]Destiny's Official "The Dark Below" DLC Trailer[/url] So this piece of evidence is my personal speculation, although many of you may also specuIate this also. It comes from the cinematic trailer for "The Dark Below" DLC, and in it Eris says, [i]"Six of us went down into the pit. Only one, crawled out. I am Eris, the last...He (Crota) took everything from me."[/i] Now this gives us an open interpretation to what it means. Does she mean by losing her fellow Guardians that everything was taken from her? Or does it mean something else, like her Light, her personality, or even her soul were taken? And we have to consider how she now appears. No Guardian in the game looks like she does, so did something or someone change her? Another good piece of evidence for this is in the "Ghost Fragment: Hive 2" Grimoire card. In this card a Guardian tells his/her story about the end of his/her life when a Hive Wizard supposedly kills her. In the story he/she tells, the Guardian says, [i]"They (the Hive) have me clamped to this spire while a black foulness eats my Light."[/i] Does this mean that he/she could be turning into a Hive, due to some reliogious ritual or simply the natural darkness of the Hive? The Guardian also says, [i]"They draw from another force, something that corrupts, that distorts, that eats and will not be satisfied."[/i] Is it just me or does this sound like it's becoming some religious ritual, "feeding" a force that corrupts and distorts? Maybe they're referring to Oryx, the god that the Hive worship? We do not know as of now, but it sounds like whatever this force is, it does have the power to "change" Guardians, creatures, or other beings. The final part of the Grimoire card is what interests me most, which is when this Guardian says, [i]"I am fading. I have no more it can take."[/i] Sounds to me like this compares very greatly to Eris's (official) speech in the trailer, when she says that, [i]"He took everything from me."[/i] What we (or I, at least) speculate is that the Hive are taking the Light from these Guardians, and due to this it probably means they are becoming Darkness, or in this case Hive. So in conclusion, it really comes down to personal belief. Out of all this evidence I've gone through, I can easily believe that Crota and possibly the rest (if not most) of the Hive were once Guardians, changed by the Darkness, Oryx, or some other entity or object. But the proof here is just crazy. I really hope that when I play "The Dark Below" tomorrow, this is what will be confirmed for me. But let me know what you guys think, and if you have any more evidence or details I left out and/or need to be added, please let me know. I have not yet played the Dark Below DLC either (This will be updated when I have), so if those lucky streamers or youtubers get on it early to play it through, please let me know what happens! I will most definitely be on tomorrow though, to see what happens with my theory. For now, keep on fighting the Darkness, Guardians!
