My guess is the mountain in the distance is a massive pile of corpses who died in the eclipse, that's where we'll see the band of the hawk, at least what remains of them in casca's mind.
Thanks for clearing it up for me regarding the whole reborn thing. Also, I have been meaning to ask since the manga does not make it very clear, and I don't know if I am supposed to know this or not yet but does Femto remember his life as Griffith or no? Also, I look forward to taking the quiz...
Would it have been more interesting story wise if Griffith had no recollection of what he did as his demon form when he was reborn into the human world? I'm not sure how the story would have unfolded but Guts trying to kill Griffith who is being guarded by Zodd, with Griffith having no idea why...
