[Suzerain of Sheol]

I tend to work on the entire story at once -- obviously over a period of time. I tend not to actually get down to the writing business until I have a solid outline laid out, which makes it easier to iron out plotholes and line things up, for me.

Though, on endings in particular, I normally don't begin with those. For the trilogy I'm still outlining stuff for, I actually began with the exact middle, then worked backwards to the beginning, and then plotted it out to the end, but it's, on the whole, a very fluid process for me.
