My take

Here's what I came up with from yesterday's elements ...

Two estranged sisters - one a sorceress, the other a thief - meet when the latter breaks into the former's workshop to sabotage an engine of war in the form of a massive obsidian crow … but which is hero and which is villain?

I think I'm just going to post my logline from here on out, unless all the elements don't show up in the logline. What I am finding out, rather quickly, is that I'm getting a side benefit of practice with character descriptions in the first two hundred words. You see, when I do describe characters (and I don't always), I do it almost right away. It's a big peeve of mine when authors describe characters several pages after their introduction. By that time, I've already formed my own mental picture. So I try to give a few key details right away. I might add more later on, but the kind of thing you immediately notice about the character, you promptly see on the page.
