Repost (with updated hints):
Like heiroglyphs from old Egyptian days,
the "teller" is gone but the story stays:
Pharaohs to heaven must pay a great fare
with riches they often postmortemly wear.
Or, if that reading is quite incorrect,
and the item in question was meant to protect,
well clearly the wearer neglected to stay,
so perhaps we conclude 'twas a curse either way.
-the answer is in a picture, part of the background in the game
-on the first continent but not in Midgar
-the answer/picture has nothing to do with the plotline
I'd say try to ascertain what the riddle is trying to talk about, even if you don't know where to find it. Lines 4, 6, and 7 are pretty key.
