The thing about all these choices is that they don't really reflect what we've seen from the Furies. The Furies don't care what you've done in your life, or what titles you carry, or what you intend to do. All these things, things like honor and status, occupation and what-not, they're ultimately meaningless. They're things that have as much weight and as much permanence as a cobweb in a hurricane.
