House of the Dragon mostly concerns itself with Targaryens or Targaryen-adjacent family members. It makes sense; they are the dynasty battling for control of Westeros. But as we’ve seen in all of HBO’s George R.R. Martin adaptations, especially Game of Thrones but also A Knight of the Seven Kingdoms, the land is vast and the population is very diverse. This fact will come into focus in season three, when Rhaenyra’s Team Black will add powerful new fighters to its side: the Winter Wolves. Leading the charge is one of Fire & Blood‘s coolest Northmen: Roddy the Ruin, more formally known as Ser Roderick Dustin. His army enters the Dance of the Dragons to defend Rhaenyra’s claim to the Iron Throne, and they’re not a bunch of fresh-faced soldiers; these are battle-tested, grizzled warriors who leave their frozen homeland to wage war while the younger generations stay behind. Cast as Roddy the Ruin is a face familiar to fans of biker drama Sons of Anarchy—Tommy Flanagan—and he’ll bring that outlaw spirit to the HBO show. Speaking to Entertainment Weekly, Flanagan and House of the Dragon co-creator and showrunner Ryan Condal teased a “ferocious” character they predict will resonate with viewers.
