Who’s Who in A Knight of the Seven Kingdoms HBO

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

Heroes are found in the most unlikely places in Westeros. In season two of Game of Thrones (lightly paraphrased from George R.R. Martin’s A Clash of Kings), Lord Varys says to Tyrion Lannister, “Power resides where men believe it resides. It's a trick, a shadow on the wall. And a very small man can cast a very large shadow.”

A century prior, it is a humble young man nearly seven feet tall with no title and no money—essentially the complete inverse of Tyrion—who must overcome appearances and prove his worth.

HBO’s endeavor at building an expanded universe around Game of Thrones continues with the series premiere of A Knight of the Seven Kingdoms, loosely based on the Tales of Dunk and Egg, a trilogy of novellas. Yes, there are Targaryens. (But no dragons.) There is also a great tourney with many familiar Great Houses, but completely new names for viewers who haven’t read The Hedge Knight, the first story in the series.

If you’re struggling to keep track of all the characters in A Knight of the Seven Kingdoms, or wondering where you recognize the actors from, here’s a handy guide to the season one cast.

Peter Claffey stars as Ser Duncan “Dunk” the Tall, a young hedge knight raised in the slums of Flea Bottom in King’s Landing, looking to prove his valor and himself worthy of a knighthood.

Egg strives to be Dunk’s squire. He’s a bit stubborn, but also extremely sharp and willing to work.

Ansell previously appeared in The Hunger Games: The Ballad of Songbirds & Snakes as a young Coriolanus Snow.

Prince Maekar is a severe man and fearsome warrior who lacks any humor. He is the fourth and last son of King Daeron II Targaryen and his wife, Queen Myriah Martell, neither of whom appear on screen in this season.

Spruell is best known for Fargo, Dune: Prophecy, and Outlaw King.

Finn Bennett as Prince Aerion Targaryen

First noted in A Storm of Swords, there is a saying in Westeros, “Every time a new Targaryen is born, the gods toss the coin in the air, and the world holds its breath to see how it will land.” There are two sides to the coin: greatness and madness. Aerion Targaryen, also known as “Brightflame,” fell on the madness side.

Bennett has also appeared in True Detective, Black Doves, and The Nevers.

On the flip side of that coin is Prince Baelor, Prince Maekar’s brother and uncle to Aerion. He is Hand of the King and Heir to the Iron Throne as the eldest son of the current ruler, King Daeron II of House Targaryen. He stands as a rare figure of restraint and patience within this family.

Carvel’s previous credits include The Crown, Jonathan Strange & Mr Norrell, and Tom Hooper’s Les Misérables.

Tanzyn Crawford as Tanselle

Tanzyn Crawford plays Tanselle, a member of a puppeteering group from the southern region of Dorne. She becomes a kindred spirit of sorts in the tourney campgrounds for Dunk.

The Australian actress previously appeared in Tiny Beautiful Things and will soon appear in the television adaptation of Assassin's Creed.

Danny Webb as Ser Arlan of Pennytree

Ser Arlan was Dunk’s first and only master to date, and whom Dunk says is the one who knighted him. (In Westeros, the rule is it only takes another knight to bestow a knighthood on another.) His influence shapes Dunk’s understanding of knighthood (and the world) more than any oath.

With nearly 200 credits to his name, Webb has appeared in movies and TV shows such as Alien, Robin Hood, Valkyrie, Doctor Who, and BBC’s Sherlock.

Daniel Ings as Ser Lyonel Baratheon

Ser Lyonel, also known as “The Laughing Storm,” is the current Lord of Storm's End and the head of House Baratheon. (He’s the ancestor of King Robert Baratheon and his brothers, Renly and Stannis, from Game of Thrones.) He’s sly as a fox and loves a good party, but ready for battle at any time.

Ings is best known for The Crown, Sex Education, and The Woman in Cabin 10.

Shaun Thomas as Ser Raymun Fossoway

A stocky but honorable Ser Raymun befriends Dunk after he arrives at the Ashford Meadow tourney. He is also a cousin of and squire for Ser Steffon Fossoway, who is seen as the more prototypical Westerosi knight in comparison.

Thomas was also in Miss Peregrine's Home for Peculiar Children, How to Have Sex, and The Choral.

Kerkour recently appeared in Lockerbie: A Search for Truth, House of Gucci, and Ridley Scott’s Napoleon.

Tom Vaughan-Lawlor as Plummer

Vaughan-Lawlor is best known for Peaky Blinders, Say Nothing, and Avengers: Infinity War.
