I'm a bit sick in this way, I think, but
I've watched the cutscenes from
Fire Warrior and read descriptions of epic space-naval battles in
Honor Guard and the Caiaphas Cain novels, and of course I watched the
Star Wars movies and
2001: A Space Odyssey. One of them probably involved co-exposure to the images in question and Tchaikovsky's music, or at least good late-19th-early-20th-century music.
So when I hear Tchaikovsky's piece from
Swan Lake, called
Dance of the Swans, what I imagine in my mind is ships maneuvering for advantage, firing on each other, and one at a time, dying as miniature suns or as smoldering hulks, and all in absolute silence. Except for that melody, soft and slow, in the background.
It's in the same way that Blizzard had the animated movie from the beginning of
Brood War, in which the defenders of a world full of ordinary people are slaughtered to the last man, to
this incongruously melodious and lovely piece.
