HAHAHA they made Corlys Velaryon black! The Velaryons, for those who haven't read the books or looked into the worldbuilding material GRRM has released to date, are a Valyrian family like their inbred overlords the Targaryens; noted for having the same pale skin, silver hair and purple or bluish-purple eyes of that race. It is precisely because of their shared Valyrian ancestry that the Targaryen royals typically married a Velaryon (by now their cousins many times over) when they aren't bedding their own sisters, because as the incest demonstrates, they were a bunch extremely concerned with the purity of their bloodlines - it's also why they only rarely married their heirs to the subject Great Houses of the setting. This particular Velaryon and his family have been consistently depicted with those Valyrian looks in all art and fanart up to this point.

The Velaryon looks are quite seriously a major story element in the Dance of the Dragons (the civil war which this series revolves around), because the crown princess Rhaenyra's first three kids look nothing like her Velaryon husband (who is gay) and a whole lot like her non-Valyrian lover. Their disputed paternity is what opens the way for her half-brother (already legally the heir, but bypassed by a sanction from their father) to challenge her claim to the throne. But I guess storytelling integrity is no match for the power of Current Year diversity, eh?

Fuck you GRRM, not only are you never going to finish your main series, but now you're selling out what little artistic integrity you still have to the woke crowd even though D&D have already crashed the TV side of your franchise with no survivors and so, if anything, only the most hardcore fans of those books you're never gonna complete are going to care to watch this series. Can't believe this guy ever entertained the title of 'American Tolkien'.
