Here's a link to one of the best pieces of genfic I've read in *ages.* It's sweet, funny, touching, and delightful, and -- best of all -- it makes you feel for Darth Vader at the same time it keeps him absolutely convincing and terrifying. The story is ophelia's "The Sith Who Brought Life Day," and it's about an Imperial officer who, as a result of a drunken bet on a hand of sabacc, winds up in a precarious position: he has to give someone a Life Day gift. He gets to choose either the person, or the gift. The officer elects to choose the gift, on the grounds that he can pick something small and inoffensive and avoid getting into trouble.
That's when his buddy tells him he's shopping for Lord Vader.
I won't spoil it for you; just go read it.
