With production continuing on Game of Thrones Season 7, there still hasn't been much released from HBO regarding new cast member or plot details, but that isn't surprising, considering how secretive last season was. Today we have a new report that claims the show has added two more cast members, British actor Joseph Quinn and Irish actor Paul Ward. While we do know who Joseph Quinn is playing, a character named Koner, no details about Paul Ward's role were given.

Watchers On the Wall broke the news, revealing that there is no character named Koner in George R.R. Martin's A Song of Fire and Ice novels, so it seems this character is being created specifically for this season. It's also possible that Koner is a fake name to disguise the real character he's playing, but we don't know for sure. As for Paul Ward, he already filmed his role in August, although no details were given for his role.

Last week, another casting rumor surfaced that singer Devin Oliver from the band I See Stars has been cast in an unspecified role, which many believe if Rhaegar Targaryen, the older brother of Daenerys Targaryen (Emilia Clarke). While we still haven't seen Rhaegar on the show yet, Bran Stark's (Isaac Hempstead Wright) greensight visions in the Season 6 finale confirmed the long-held fan theory "R+L=J," meaning Jon Snow's (Kit Harington) real father is actually Rhaegar Targaryen and Lyanna Stark, the sister of Ned Stark (Sean Bean). It had been long established that Jon was the bastard son of Ned Stark, but in the Season 6 finale, this fan theory was proven to be true.

While it was never confirmed that Devin Oliver has landed a role, the singer, who would be makling his acting debut in Game of Thrones, bears quite the striking resemblance to Emilia Clarke's Daenerys Targaryen, and also her late brother Viserys (Harry Lloyd), who was brutally killed by Khal Drogo (Jason Momoa) in the first season. After the rumor surfaced, a well-read Redditor pointed out that, in George R.R. Martin's books, Rhaegar sung a song at Harrenhall that brought tears to Lyanna's eyes. It's possible that, if Devin Oliver has been cast as Rhaegar, his singing skills will be put to use.

It's worth noting that, in the 10 months between Season 5 and Season 6, HBO didn't confirm any cast members whatsoever, so we likely won't get any confirmation on this report until Season 7 debuts next summer. The hit fantasy series based on George R.R. Martin's novels recently started filming Season 7, a few months later than usual, since the arrival of winter in Westeros requires a colder climate for the production. Hopefully HBO releases some new details about Game of Thrones Season 7 soon, as production continues.
