Three new trailers for "Game of Thrones" season 6 tease the fate of the three prominent Houses in Westeros.

HBO recently unveiled the latest set of trailers for the sixth season of the TV adaptation of George R.R. Martin's bestselling book series "A Song of Ice and Fire." Each trailer shows the banner of the three noble houses combined with the voices of the biggest threats in the upcoming season.

One of the videos shows the House Lannister banner that is almost wrecked to bits. The High Sparrow (Jonathan Pryce) can be heard on the clip saying: "Every one of us is poor and powerless — and yet together, we can overthrow an empire."

Though the High Sparrow does not give a specific detail in the clip, it could be speculated that his religious movement could easily overthrow the Lannister empire, especially now that Tywin (Charles Dance) is already dead, Tyrion (Peter Dinklage) remains on Meereen, Jaime (Nikolaj Coster-Waldau) is still in Dorne and Cersei (Lena Headey) has been stripped from power after being charged by adultery.

Meanwhile, another teaser shows the equally tattered House Stark banner. But this time, the ruthless Ramsay Bolton (Iwan Rheon) can be heard in the background claiming "Winterfell is mine. Come and see."

In season 5, viewers saw Sansa Stark (Sofie Turner) forced to marry Roose Bolton's (Michael McElhatton) son. Since they thought that all Stark men were already dead, the Boltons believed that Winterfell already belongs to them.

Finally, the last clip shows the banner of House Targaryen, which is almost as ruined as the other two house banners. A voice can be heard in the Dothraki language, telling Daenerys Targaryen (Emilia Clarke) "You are nobody, the millionth of your name. Queen of nothing."

Daenerys's fate remains uncertain as her late husband's traitor Khal Jhaqo found her roaming around after the people of Meereen threatened her life.

HBO will release the premiere episode of "Game of Thrones" season 6 on April 24.
