Rhaenys Targaryen: Team Black

Older than her cousin Viserys, but passed over for the Iron Throne simply because she’s a woman, Rhaenys (Eve Best) is a fierce dragonrider as well as a source of wisdom and—for both Rhaenyra and Alicent in season one—full of reality checks about how Westeros’ patriarchal system prefers to conduct itself. She’s married to Lord Corlys Velaryon; while both their children died (or “died,” since their son faked his death) in season one, they have two granddaughters in Daemon’s kids Baela and Rhaena.
