Who Are the Greens and the Blacks on 'House of the Dragon'?

House of the Dragon should theoretically be easier to follow than Game of Thrones was. It’s about two branches of the same family, and there are only two sides you can be on: Green or Black. The early days of GoT followed the War of the Five Kings, so it follows that dealing with just two monarchs should be easy, right?

Wrong, because nothing is ever easy in Westeros. Targaryen naming conventions mean that multiple HOTD characters have the same name, and nearly all of them have at least one “ae” diphthong. The colors also don’t really help, given that the Greens’ chosen shade is so dark it’s almost black, and both sides are still using the Targaryen three-headed dragon symbol.

In the spirit of making things a little easier to follow, keep reading for a complete guide to who’s who on both sides in the Dance of the Dragons.

Alicent Hightower (Olivia Cooke)

Alicent is the dowager queen of Westeros, having been married to the late Viserys Targaryen (Paddy Considine). She essentially started the war by misinterpreting Viserys’ deathbed recounting of his dream of the Song of Ice and Fire.

Aegon Targaryen (Tom Glynn-Carney)

Aegon, known as Aegon II, is the eldest son of Alicent and Viserys. He becomes King of the Seven Kingdoms in Season 1, although that claim is contested by his half-sister, Rhaenyra (who is the leader of the Blacks). His dragon is Sunfyre.

Larys Strong (Matthew Needham)

Larys, otherwise known as the foot fetish guy, is the younger brother of Ser Harwin Strong (who died in Season 1 but is thought to be the biological father of Rhaenyra’s children with Laenor Velaryon). Aegon recently named Larys his Master of Whisperers.

Rhaenyra Targaryen (Emma D’Arcy)

Rhaenyra is the only child of Viserys and his first wife, Aemma Arryn. Viserys always wanted Rhaenyra to be his heir despite the fact that she is a woman, which makes her unfit for the throne in the eyes of many Westerosi. She declared herself Queen of the Seven Kingdoms in Season 1 while her younger half-brother Aegon was crowned in King’s Landing. She has three children with her first husband, Laenor Velaryon, and two with her second husband, Daemon Targaryen. Her dragon is Syrax.

Daemon Targaryen (Matt Smith)

Daemon is the younger brother of Viserys and the second husband of Rhaenyra (so yes, he’s also her uncle). He supports his wife’s claim to the throne but also definitely thinks he deserved the crown after Viserys’ death. Daemon and Rhaenyra have two children together who are confusingly named Aegon and Viserys. His dragon is Caraxes.

Rhaenys Targaryen (Eve Best)

Rhaenys, known as the Queen Who Never Was, is the first cousin of Viserys. While she had a strong claim to the throne at one point, her grandfather Jaehaerys I named Viserys his heir instead. She doesn’t seem to like Rhaenyra very much, but she also doesn’t want to see her excluded from the throne because of her sex, as she was. Her dragon is Meleys.

Corlys Velaryon (Steve Toussaint)

Corlys, known as the Sea Snake, is the leader of House Velaryon and the husband of Rhaenys. While he thinks his wife has the best claim to the throne, he supports Rhaenyra because her sons are betrothed to his granddaughters, which means they could eventually become queen.

Mysaria (Sonoya Mizuno)

Mysaria, aka the White Worm, kind of does her own thing, but for now, she’s on Team Black. She helped Daemon find Blood and Cheese for the assassination of Jaehaerys, and she appreciates that Rhaenyra set her free to go back to King’s Landing (which could come in handy later).
