That was a really good finale, especially that dragon fight at the end.
That was a big whoopsie from Prince Aemond at the end there.
I mean it was tragic that Lucerys, one of the youngest and most moral characters died so suddenly.
But Aemond kinda did look like he was about to say "Oh Fudgesicle!" And that made it kinda funny
The Blacks or the Greens?
Neither! They both just started a war over power. Though the show does go to some lengths to morally upgrade quite a few of the characters when compared to the source material.
I would also like to add that the Dragons featured in GoT and HotD are technically Wyverns.
Really only if we go by Dungeons and Dragons and works derivative of it.
In real life Medieval Times people didn't have strict categories when it came to dragons/wyverns/worms. What they called dragons could take any shape of the ones you posted, or even stranger ones. Words like wyvern and (great) worm/wyrm were sometimes used regionally (and especially for heraldry), but they were never completely or cleanly cleanly from dragons, many European languages that have dragons in thier mythology don't even have a word for Wyvern.
It was only DnD that strictly separated them into different things, and that bled over into a lot of fantasy inspired by it.
And, in additon to that, in the Song of Ice and Fire universe giant, fire-breathing reptiles with two legs and two wings are Dragons, as established by the creator of that universe, GRRM.
