It seems like the production of the sixth season of "Game of Thrones" is nearly over, after different reports about wrap parties start to circulate online.

Actresses Emilia Clarke, Sophie Turner, and Maisie Williams were spotted together Sunday during the show's season 6 wrap party held at the Ulster Museum in Northern Ireland. The actresses portray the roles of some of the fan-favorite characters in the TV adaptation of George R.R. Martin's "A Song of Ice and Fire" saga.

Clarke, who plays Daenerys Targaryen in the series, posted a photo of Turner and Williams on Instagram. The two other actresses portray the roles of sisters Sansa and Arya Stark, respectively.

Another partygoer posted a photo of the three actresses together during the party.

According to reports, Liam Cunningham also attended the wrap party. He is known in "Game of Thrones" as Davos Seaworth.

Aside from the wrap party that happened in Belfast, other reports say actor Kit Harington was also spotted around the area. It could mean that his character Jon Snow, whose fate had been a subject of endless debate after the "Game of Thrones" season 5 finale, is alive when the series returns in April.

This theory is strengthened by reports saying that Carice van Houten, the actress who portrays the role of the Red Witch Melisandre in the series, was also seen on the show's Belfast set.

Viewers believe that Melisandre could have brought Jon Snow back to life in season 6. With the two actors seen on the same set, it could mean that the fan theories could be accurate.

Aside from the return of Harington, fans of the show were also delighted to find out that Isaac Hempstead Wright will reprise his character Bran Stark in the series. Bran was not seen in the entire fifth season of the show.

"Game of Thrones" season 6 is slated to premiere in April 2016.
