Uh yes the fuck they are. North, Iron Islands, The Vale, The Westerlands, The Reach, the Stormlands, and Dorne are the 7 kingdoms. It's the Riverlands which aren't actually one of the kingdoms. At the time that Aegon conquered Westeros the Riverlands belonged to the Iron Isles, and the Ironborn King was known as the King of the Isles and Rivers.
Hows that Bandwagon?
lol. I'm not convinced that's not just a foil so that the audience isn't bored by how one sided this "War" is. If they decide that a ballista can kill a dragon the TV show that's fine, completely different from the books, but that's cool with me.
However, I hope that was just a prototype and that they're building much larger versions and manning all the towers with them. Shooting a 300 year old dragon skull from 15 feet away is much different from shooting at a moving dragon flying 300 feet above you melting your shit.
They can still go the book route, it's the scales that deflect arrows and projectiles as the dragons age, not the bones. GRRM tried to go as "realistic" as possible with dragons (he debated even including actual dragons, was originally going to use magic instead). That's why they are actually "Wyverns" since the only flying creatures with wings + arms/legs are insects, larger animals arms evolved into wings rather than a 3rd set of appendages sprouting out of their back. iirc dragon bones are supposed to be hollow like bird for weight for flight, just a higher iron content or something. it's been a while.
