Legendary Comics and Line Webtoon will debut a new imaginative comic series Acursian starring John Barrowman (Doctor Who, Torchwood, Arrow) in September.

The series—rooted in Celtic lore in a unique fusion of mythic storytelling from co-creators John Barrowman, Carole Barrowman (Torchwood), and Erika Lewis (Game of Shadows and Firebrand: The Initiation of Natali Presano) with art by Beni Lobel and designs by Tommy Lee Edwards—will be available beginning Thursday, September 13. Readers can download the official Webtoon app by visiting the Apple App Store and Google Play.

Barrowman is Charlie Stewart who, on the eve of an important birthday, falls victim to an ancient Celtic curse.

Stewart seemed to have it all: the big house, the fast car, the beautiful family, and a high-power career at a leading criminal law firm, but overnight finds everything spiraling out of control as his perfect life becomes a disaster zone of chaos and calamity. Every decision he makes, every relationship he has, every choice he’s given is doomed to fail spectacularly, no matter what he does.

Embarking on a quest for the truth behind the supernatural forces re-writing his destiny, Charlie discovers that his ancestor Bonnie Prince Charlie made a deal with the ruthless Celtic God of War, Bregon. In return for the Bonnie Prince’s victory at the battle of Culloden, Bregon demanded the prince steal three magical talismans from Bregon’s own sisters. These sisters cursed the entire Stewart bloodline and now Charlie must settle a centuries-long family squabble among gods in order to get his own family back. Real life and ancient legend collide in unexpected ways as Charlie battles across this world and opens up realms of time and mystery that no mortal was ever meant to see.

This isn’t the Barrowman siblings first dip into comics as the pair previously collaborated on the DC Comics digital Merlin The Dark Archer series. It’ll be interesting to read this team’s take on the Barrowman’s Scottish heritage in Acursian when it debuts in Septmeber.
