HBO has released two preview clips from “Game of Thrones” season five, along with a slew of new photos that include a first look at Oberyn Martell’s (Pedro Pascal) deadly daughters, The Sand Snakes, who are out for revenge after their father’s gruesome murder at the hands of The Mountain (Hafþór Júlíus Björnsson) last season. The images also feature Cersei Lannister’s (Lena Headey) daughter Myrcella Baratheon (Nell Tiger Free), who is currently in Dorne, where she is expected to marry Oberyn’s nephew, Prince Trystane Martell (Toby Sebastian) when she comes of age.

Watch the season five sneak peeks below:

The first preview clip sees Tyrion Lannister (Peter Dinklage) discussing his unlikely escape from King’s Landing with Lord Varys (Conleth Hill), who freed him from the Red Keep because Tyrion’s brother Jaime (Nikolaj Coster-Waldau) asked him to — but was that the only reason for Varys’ uncharacteristic altruism?

In the second clip — an extended look at a scene that was previously released through the “GOT” viral marketing campaign “The Sight” — Jon Snow (Kit Harington) challenges Mance Rayder (Ciarán Hinds) to put aside his pride and work together with Stannis Baratheon (Stephen Dillane) for the sake of his Wildling followers.

“Game of Thrones” season five premieres Sunday, April 12 at 9 p.m. on HBO.
