I'm not sure whether it's a story with a long digression in the middle, or a story with a long framing device bookending it, but either way an odd construction—a tale split in the middle by another story as long as the rest combined. That middle story is the more vivid one to me, the characters more fleshed out, the setting more vivid, and that sort of works given that the middle story is meant to be almost an infection, capable of carrying additional details even if they aren't told.

The outer story drapes itself in the weight of loss, and I don't know that it quite carries it. Those human elements aren't what has stuck with me, at least. Not in the same way as the more fairy tale-like middle story, which spans generations and continents. That one is a story of duelling dark magicians, more compelling but I guess less weird than a lonely fisherman stumbling onto the fringes of that story. So what this really is, is a weird story that manages to explain itself without losing its impact.
