Details regarding the season 6 plot of HBO's "Game of Thrones" have been few and far between. But a set location has sparked speculation that viewers will finally see the death of a character that has been due for several seasons.

For instance, filming has been taking place at an Irish rope bridge, and readers of George RR Martin's "A Song of Ice and Fire" series believe it won't be long before Balon Greyjoy--Theon's father--dies.

Watchers on the Wall, a website that describes itself as a "Game of Thrones" community for breaking news, reported that filming has been taking place in Ballintoy and an eagle-eyed spectator even noticed the Greyjoy crew near the Carrick-a-Rede bridge.

So how does Balon Greyjoy die? In Martin's books, a strong wind coming from the west was responsible for the death of the old King, who was crossing the bridge. But according to a new Vanity Fair report, the Faceless Men might have something to do with Balon's death.

The publication points out that earlier in the third book entitled "A Storm of Swords", Arya Stark overhears a prophetic dream that could have been a reference to Balon's death.

The passage from the book that reads "a man without a face, waiting on a swaying bridge, on his shoulder perched a drowned crow with seaweed hanging from its wings" could have been about Balon's death, the publication speculates, adding that the man without the face could have been a reference to the Faceless Man, something Arya is now training to become.

Balon's death would mean that season 6 will explore the plot popularly referred to as the Kingsmoot, which is the battle between the Ironborn to take over Balon's throne.

Season 6 will also introduce viewers to Euron Greyjoy, the younger brother of King Balon Greyjoy, and the eldest uncle of Theon and Yara Greyjoy.

It was recently revealed that HBO has cast Danish actor Pilou Asbæk as Euron Greyjoy, and he was reportedly spotted shooting what is suspected to be the Kingsmoot scene around Ballintoy Harbour.

"Game of Thrones" will be back with season 6 in early 2016.
