The major players in "Game of Thrones" will finally meet their fate in the eighth season. Daenerys Targaryen and Cersei Lannister are expected to fight for the Iron Throne while Jon Snow rallies the living in the battle against the White Walkers. But what about the other supporting characters in the HBO series? There is a possibility that Ser Davos Seaworth will be more than just the King in the North's loyal advisor in Season 8.

Davos Seaworth might not be the most popular character from the show, but The Onion Knight has certainly made his mark. Although he started out as Stannis Baratheon's advisor, Davos eventually decided to stand by Jon Snow.

Luckily, it looks like Davos made the right decision when he allied himself with the former Lord Commander of the Night's Watch. Will he play an important role in "Game of Thrones" Season 8?

Davos joins the Game in final season

There have been a few theories about the Onion Knight ever since he started supporting the King in the North. Some believe that Davos might represent Lightbringer, the flaming sword wielded by Azor Ahai. A darker theory suggests that he will be Jon Snow's only surviving ally in the eighth season of "Game of Thrones." But is it possible that Davos will simply be another man who will rise to power just by making the right alliances?

There are speculations that Shireen Baratheon's beloved friend will be named Hand of the King by Jon Snow. The final season could conclude with Jon taking over as ruler of the Seven Kingdoms [VIDEO], and he could choose to make Davos his most trusted advisor.

Unfortunately, this could mean that the Mother of Dragons will not take the Iron Throne for herself.

But what are the chances that Davos Seaworth's journey will lead him to a seat in the High Council in King's Landing? Liam Cunningham has admitted that George R.R. Martin shared a secret with him about the final season of "Game of Thrones." Could it be connected to the Onion Knight?

Liam Cunningham teases 'GoT' secret

In an interview with Huffington Post, the "Clash of the Titans" star confirmed that the author of "A Song of Ice and Fire" once revealed interesting details about the final season of "Game of Thrones." However, Cunningham tried to downplay the hype by stating that "it’s not monumental" at all.

"Everybody thinks he told me who’s on the throne because that’s what they’re projecting," Liam Cunningham said before adding that, "it ain’t that big." According to the "Philip K. Dick's Electric Dreams" actor, "It was just something he told me." Nevertheless, fans are hoping the secret is related to Davos Seaworth's fate in Season 8.
