We have an update on the potential Supernatural spinoff that will air as a backdoor pilot in early 2014 on The CW.

According to Deadline sources, the series will be set in Chicago and will delve into the contrasting/clashing cultures of hunters and monsters in that city.

Look for this special installment to center on an unannounced, not-yet-cast character and for it to be written by supervising producer Andrew Dabb.

UPDATE: Producer Robert Singer adds of the spinoff: "We’ll have main characters who are both human and monsters," along with “families of monsters and families of hunters... It’s much more of an ensemble than Supernatural."
