Deadline reports that this would be essentially Gaiman’s Lucifer, saying,
That hire means that the guy who did Californication is doing a show about Lucifer making his way through California, and that makes a weird sort of perfect sense.
This version of Lucifer was introduced early in Sandman. His first appearance there was very much as an antagonist. But in the ‘Season of Mists’ storyline, Morpheus, the personification of dreams, goes to Hell in an attempt to free Nada, a woman he had imprisoned there centuries earlier.
In Hell Morpheus finds Lucifer to be surprisingly accommodating, and in fact receives a strange gift from the fallen angel: the key to Hell. Lucifer bails on his gig as ruler of that realm, leaving the choice for a new ruler to Morpheus. Eventually, after a stint in Australia, Lucifer sets up shop in Los Angeles as described above.
A Lucifer TV series could be one way to introduce Sandman characters without diving full-on into a series based entirely on Gaiman’s stories. But with a big-screen Sandman developing and WB maintaining different lines of continuity between TV and film projects, don’t expect that to happen.
