House of the Dragon films at Driftmark, seat of House Velaryon

The other day we reported on what looks like the first outdoor set for House of the Dragon, HBO’s follow-up to Game of Thrones. Nothing’s technically confirmed, but the signs are all there: we know House of the Dragon is starting filming around now, and the castle set on the island of Saint Michael’s Mount in Cornwall, England looks awfully Thrones-ish, I think we can all agree:

Since then, Cornwall Live has released even more detailed photos, and fans have zoomed in on the sigil above the stone archway in the picture above. Upon closer inspection, it looks an awful lot like the silver-and-green seahorse of House Velaryon:

What is House Velaryon and why is it important?

House Velaryon is a key player in the Dance of the Dragon, the Targaryen civil war at the center of the new show. They have their seat on an island called Driftmark not far from King’s Landing. Once again, things are matching up, since this film crew is filming on an island. I’m betting that we’re looking at the Velaryon’s castle seat, High Tide.

House Velaryon is headed up by Corlys Velaryon, an experienced mariner who will be played by Steve Toussaint on the show. Their whole thing is naval power. The Velaryons control a lot of ships, and you’d best believe they’re going to use them to try and get their chosen candidate on the Iron Throne.

Again, none of this is technically confirmed, but it doesn’t take a genius to read the signs. We’ll probably see more filming sites over the next couple of months. The first season of House of the Dragon is due out in 2022.
