Valar Dohaeris

The episode's title translates to "all men must serve" in the High Valyrian language in George R. R. Martin's A Song of Ice and Fire novels, which the series adapts.

The title mirrors that of season 2's finale, "Valar Morghulis" – "all men must die.” The episode received mostly positive reviews, with many praising its performances and strong ability to reintroduce many of the series' plotlines.

Samwell Tarly is saved by the direwolf Ghost and Lord Commander Jeor Mormont, who reprimands Sam for failing to warn of the approaching army and orders the survivors back to the Wall.

Reaching Astapor in Slaver's Bay with her fast-growing dragons, Daenerys Targaryen considers buying an army of the "Unsullied", renowned eunuch soldiers.

[3] "Valar Dohaeris" introduces the Irish actor Ciarán Hinds as the Wildling leader and Night's Watch deserter Mance Rayder, one of the latest Season 3 roles to be cast.

[5] The season premiere also marks the first appearance of guest stars Kristofer Hivju as the Wildling Tormund Giantsbane, Nathalie Emmanuel as the slave Missandei, and Anton Lesser as the wounded prisoner Qyburn.

Actor Ian Whyte, previously cast as a White Walker in the first season, was recast as the huge Ser Gregor Clegane in the second and appears in the episode as the giant seen in the wildlings camp.

After immersing himself in the fictional background, Peterson ended up devising two languages: High Valyrian, the oldest form that was spoken at the height of the Empire and that in its purest form still exists as a language of scholarship and refinement, and the Slaver's Bay variety of Low Valyrian, a creolized version that is spoken in local dialects around the Slaver's Bay.

Tyrion and Bronn are seen walking on the famed city walls, and the scene where Lord Baelish visits Sansa at the docks was filmed in the old port between Fort Lovrijenac and the Pila Gates.

The fires burning inside the tent made the set very hot, and the actors suffered the heat wearing heavy furs designed for Arctic climates.

The Unsullied are introduced in the city ramparts of Skala de la Ville, the 18th-century sea bastion that runs along the northern cliffs, and during the closing scene when Barristan reveals himself, the Genoese-built citadel by the harbour can be clearly seen.

The episode is dedicated to the memory of cinematographer Martin Kenzie, who worked in the photography department and died of cancer while the third season was being filmed on July 16, 2012.

The website's critical consensus reads, "'Valar Dohaeris' overextends itself trying to reintroduce a multitude of characters and plotlines, but is strengthened by its brilliantly acted two-person scenes (and three growing baby dragons).

She also praised the show for taking "creative liberties which always pay off in bucket loads," commenting on how this can "add to Martin’s world and flesh it out in new ways.

The episode used locations in four different countries: The Paint Hall in Belfast, the City Walls of Dubrovnik, Mývatn and Vinderbelgjarfjall, and the Old Fort at Essaouira.
