dunno if this has been discussed but...
given all the theorises about how the gullwings travelled from spir to gaia at some point thousannds of years ago
this seems to me very similar to what genova did 2 thousnad years prior to the game and what sephiroth tries to do but gets his ass kicked
anyone think its possible that genova coulda came from spira?
possibly genova was a sinspawn or something?
probably a lot of holes in this but i think it would be pretty cool if it was the case
