Hmmm... a disappointing number of responses so far. I'll give it another day before handing out too many specific clues. NGU, thank you for doing such a thorough breakdown. You're very close or partly correct in a couple of places.
I will make a couple of comments based on whats been said so far. There isn't much filler in this riddle. It is very hard, but most of the details aren't pointless. Also, the showing working as has been done is probably all anyone is gonna get at the moment, this is a VERY hard riddle, and there are a couple of leaps needed, but no one is near that stage yet.
I will say this, as I realized an extension of NGU's answer to one line is wrong but fits just as well as the actual answer...
"Life’s story told in a place to mend." Does not refer to Mideel.






It is big, I've done my best to make sure there's nothing too obscure in it, but it is damn hard, and a couple of steps really might take some hints, we'll see... Your guess was pretty good, but only partly correct. I'm not gonna say much just yet, I might start handing out clues in an hour or so, but it'd be nice to have some more ideas first. I'll say outright, I doubt anyone will get this entirely soon. I've tried to do something a bit different with this one, and while I think there are enough clues in there to show what to do, its by no means obvious
