A crow is joining the world of dragons.

Kit Harington, who plays the Night’s Watch-man Jon Snow on Game of Thrones, will voice a new character in How To Train Your Dragon 2, DreamWorks Animation announced at Comic-Con today.

Also joining the sequel’s cast is Cate Blanchett, who played elven guardian Galadriel in The Lord of the Rings and The Hobbit movies, and Djimon Hounsou, best known as the enslaved warrior Juba in Gladiator.

The revelation came at the end of the DreamWorks Animation panel at the annual gathering of geekdom in San Diego, with writer-director Dean DeBlois describing some of the plot details from the upcoming family adventure, due in theaters next June.

After the vikings and the dragons settled their war in the 2010 movie, the previously hostile tribes of humans and flying beasts have teamed up to explore the world together. Scrawny-but-innovative viking Hiccup (voiced by Jay Baruchel) has even developed a flying suit (pictured above) that allows him to soar through the air alongside his dragon partner Toothless.

They end up in a distant land where the humans are not only still locked in battle with the dragons, but have found a way to enslave them and are trying to harness a dragon army to conquer other lands. Harington plays the lead dragon-trapper, Eret, and Hounsou is Drago Bludvist the maniacal leader building the force.

Blanchett co-stars as Valka, who prefers scaly company to humans, and works as a reclusive vigilante who rescues the dragons from their traps and secrets them away to a sanctuary in the arctic.

As DeBlois announced the new characters, Harington made a surprise appearance at the end of the panel.

The world of Dragons 2 is obviously far less gruesome than Game of Thrones, but DeBlois is a huge fan of the HBO series, which is why he recruited Harington.

“He’s my favorite character on the show, he has a youthful voice but a lot of texture and mobility,” DeBlois tells EW. “There’s a toughness and cockiness, but a vulnerability and a sense of misplaced loyalty in Eret. He begins as a villain, but there is potential for redemption in him.”
