A pilot for a Supernatural prequel series has been ordered, which is set to tell the story of Dean and Sam’s parents Mary and John Winchester.

The show, entitled The Winchesters, will be coming to US network The CW should it be greenlit for series production. It will feature original series star Jensen Ackles reprising his role as Dean Winchester to act as its narrator. So far, he’s the only original cast member slated to return.

However, Supernatural writer Robbie Thompson is set to return as both a writer and executive producer.

Having run for 15 season and 327 episodes, Supernatural is one of the more successful TV series of recent years. Other attempt shave been made to get spinoffs happening, but The Winchesters is the first to get to the pilot stage.

Here’s a trip down memory lane:
