Outcasts and Camelot star Liam Cunningham has signed up for the second season of HBO’s epic fantasy series Game of Thrones.

Cunningham, who played President Tate on the short-lived BBC drama, will play Davos Seaworth, a former smuggler who earned the nickname the “Onion Knight” for his history of smuggling onions among other things. Seaworth will become a great supporter and confidante of Lord Stannis Baratheon, the rightful heir to the throne, played by another newcomer to the show, Stephen Dillane. Carice van Houten has been cast as Stannis’s counsellor, Melisandre, an intimidating woman who has the ability to see visions of the future in fire.

Gwendoline Christie and Natalie Dormer have also joined the show, based on George R.R. Martin’s A Song of Fire and Ice novel sequence. Production on the new series begins next Monday, July 25, in Ireland.
