Lux is the star of Martin Millar's excellent Lux the Poet and co-star of his comic book Lux and Alby Sign On and Save The Universe. He is a disconcertingly attractive, outrageously vain young man with a shock of red and yellow hair and a head full of drugs and poetry.
Lux spends most of the novel stumbling around Brixton with a riot going on around him, trying to get on television and to find the love of his life, Pearl, and make sure she is safe. Pearl is a confirmed lesbian but, says Lux, 'everyone knows that that kind of thing doesn't apply to young poets in love'.
In Neil Gaiman's The Sandman, Lucifer opens a nightclub named Lux after retiring as ruler of Hell and handing his key over to the Dream King to take care of. The devil plays the piano and looks after the running of the place; a devoted demon lover works in the bar, keeping the hideously deformed half of her face always hidden behind a mask. In The Kindly Ones, Lyta Hall is attending a job interview at the Lux when her child is taken captive.
