House of the Dragon

House Velaryon, the Sea Snake's family, was reimagined as Black, a notable departure from the books where they are described as silver-haired Valyrians.

• Corlys Velaryon and his family depicted as Black
• Princess Rhaenys and the Velaryon children cast accordingly

The show centers female claimants to power and the theme of a patriarchal society denying women rule, but men are not uniformly mocked or made incompetent foils.

• Rhaenyra's struggle for the throne against male relatives
• Alicent and Rhaenyra as central power players
• Rhaenys' commentary on women's limited power

Includes a recurring queer subplot with Laenor Velaryon and a same-sex relationship, plus other implied bisexual dynamics, but it's woven into the narrative rather than foregrounded as messaging.

• Laenor Velaryon depicted with male lovers
• His arrangement with Rhaenyra and faked death to be with a lover

The Velaryon recasting introduced diversity into a Valyrian bloodline that lore describes as uniformly silver-haired, a noticeable lore-adjacent choice in an otherwise setting-consistent cast.

• Velaryon family race change despite Valyrian heritage in the books

Themes of women's disempowerment surface in dialogue but the show stays largely focused on political intrigue rather than sermonizing.

• Rhaenys' speech about the order of things to Alicent
• Recurring lines on women being denied agency

Power, cruelty, and folly are spread across genders; no consistent framing of masculinity as inherently toxic.

Largely faithful to Fire & Blood, with the main deviation being the identity-related recasting of the Velaryons; most other changes are ordinary adaptation choices.

• Velaryon racial reimagining vs. book description
• Condensed and dramatized events from the source text
