## The New Blood

Season 3 isn’t just about old grudges — it’s recruiting an army of newcomers ripped straight from George R.R. Martin’s *Fire & Blood*:

- **James Norton** as Lord Ormund Hightower, commanding a powerful Green army
- **Tommy Flanagan** as Ser Roderick “Roddy the Ruin” Dustin
- **Dan Fogler** as Ser Torrhen Manderly
- **Barry Sloane** as Ser Adrian Redfort
- **Annie Shapero** as Alysanne Blackwood

This influx of warriors and lords signals exactly how massive the war is about to get, with new armies entering the fray on both sides of the conflict.
