“The 100” has promoted recurring guest star Zach McGowan to series regular in Season 4, TheWrap has learned.

The “Black Sails” actor made his debut as a Grounder named Roan in Season 3. Throughout the season, Roan went from enemy to uneasy ally for Clarke (Eliza Taylor), Bellamy (Bob Morley) and the rest of the Arkers, and ended the series as King of the Ice Nation.

McGowan’s promotion comes after series regular Ricky Whittle exited the show halfway through Season 3.

The series is centered on 100 juvenile delinquents who are sent down to a potentially toxic Earth to test its habitability, and also stars Marie Averopoulos, Paige Turco, Henry Ian Cusick and Isiah Washington.

“The 100” is based on the book series by Kass Morgan and is produced by Bonanza Productions Inc. in association with Alloy Entertainment, Warner Bros. Television and CBS Television Studios.

Jason Rothenberg created the show and is the executive producer. Now filming, Season 3 of “The 100” is slated to air on The CW in midseason 2016.

McGowan most recently starred on Starz’s “Black Sails” and was a series regular on Showtime’s “Shameless.” He also had a supporting role in “Dracula Untold” opposite Luke Evans and he is represented by Innovative Artists & Primary Wave Entertainment.
