Ah, it's been long enough that I'd forgotten some things so I went to reread and realized that only two chapters had been posted on ff dot net. Any chance you'll be polishing and posting the rest of it there?

Having read through the comments, I like your reasoning for what Sephiroth did; ruthlessly logical for someone whose hopes are pretty much slim and none. Also like that it all comes down to strategy, tactics, and how everything in his life relates in military terms, that being one of the strongest influences on Seph's psyche. Kudos for showing that.
