Ooo that spikes a new theory of mine, with the mentioning of Nephilim being part of teh Gnosis @_@
So here goes...
KOS-MOS can use X-Buster, which is alot like Proto Merkahba's Attack where it takes in the Gnosis, (hence that big glob of Sophita Pia was born)
So what powers KOS-MOS is the Gnosis I believe, somehow Nephilim could be made from that.
But I still think Nephilim is KOS-MOS' subconsciousness, because we've seen her in the beautiful mind of KOS-MOS dear o.O;;;
Shion/Gnosis - Well with that Realian theory running around about Shion is half Realion, still doesnt exempt her from the fact that she can't turn Gnosis like Betty. Here are some wierd things that happen to Shion, that WHY she didn't die from.
Exhibit A- When someone threw that A.G.W.S. Size hand-granade in the Hall during the Attack on the Woglinde. Everyone else died around her, and Shion was the only survivor!!! WHAT?!!!
Exhibit B- Shion was turning Gnosis, thank goodness for our blue-haired angel that she stopped that. Not to long after, Cherenkov was touched by, or rather grabbed by a Gnosis, and not so long after that he turned into one.
I have no theories for Exhbit A except Shion is not your average person ;D
Exhbiti B- Either chaos, or the Zohar had something to do with Shion not transforming into A Gnosis, either that it was Nephilim.
Okies I take back what I said about Nephilim being KOS-MOS' subcounsciousness, but its still a possibility.
