The CW’s Supernatural spinoff has found two of its leads: Aussie actor Nathaniel Buzolic (who played Klaus’ brother Kol on The Vampire Diaries last season) and British actor Lucien Laviscount (Skins, Coronation Street) have been cast in key roles in the Chicago-based Tribes.

While these characters are two leads on the show, we hear Tribes plays more like an ensemble drama compared to the flagship series, so there are other important roles yet to be filled. Tribes is described as a “sweeping drama about the various mafia-esque monster families that unknowingly-to-humans ‘run’ the underbelly of Chicago and who are being tracked by a newly-minted Hunter who’s trying to stop them and rid Chicago of anything or anyone supernatural.” The project from writer-producer Andrew Dabb will debut its pilot as an embedded episode of Supernatural on April 29.
