She didn't choose to violate genre conventions. She doesn't read fantasy in the first place, and Harry Potter wasn't intended as a (high) fantasy.
In an interview with The New York Times, J. K. Rowling said the following:
Any literary genre you simply can’t be bothered with?
“Can’t be bothered with” isn’t a phrase I’d use, because my reading tastes ...
Who is more powerful, the President of the United States or the marine guarding him? In personal one-on-one combat I'm certain the marine would defeat the President. However, it is the President that commands the military of the United States.
Similarly, other Middle-earth creatures may have been more powerful individually (Balrog, Dragons, etc) but ...
It is just something that Dragons do in Tolkien's legendarium. It's in their nature. From The Hobbit:
Dragons steal gold and jewels, you know, from men and elves and dwarves, wherever they can find them; and they guard their plunder as long as they live (which is practically forever, unless they are killed), and never enjoy a brass ring of it. Indeed they ...
We find out later in the book, when Sirius writes to Harry after the task:
Congratulations on getting past the Horntail. Whoever put your name in that goblet shouldn’t be feeling too happy right now! I was going to suggest a Conjunctivitis Curse, as a dragon’s eyes are its weakest point — “That’s what Krum did!” Hermione whispered — but your way was ...
The idea that dragons were once numerous, but are no longer, is just one of many manifestations of what TV Tropes calls the "The Magic Goes Away" (named for the Larry Niven story). It is really one of the most common and fundamental tropes in fantasy—that the world of the past was more magical and fantastical than the world we live in now—and it traces its ...
Dragons in Harry Potter are indeed powerful.
Though it’s true that dragons were used in one of the tasks of the Triwizard Tournament competed in by schoolchildren, dragons were shown to be powerful creatures. The task wasn’t actually to defeat a dragon, just to retrieve an egg guarded by one. To defeat a dragon, Sirius Black says would need about six ...
I think this is inspired by real life.
Consider that where I live - the island of Ireland - was once a habitat for elk, wolves, wild cows and many species of deer.
Over the last thousands of years they have been killed off, or couldn't adapt to environmental changes.
The wolves were common in Ireland in the 17th century (see Wolves in Ireland) and my ...
It sounds like Eragon by Christopher Paolini. Published in 2003 but it looks like the German translation wasn't published until 2009. The film was 2006.
Eragon finds a dragon egg and it hatches. He bonds with it and becomes a dragon rider.
Big Bad Galbatorix has his own dragon and had all the other riders killed.
There are elves.
There was a film that a ...
It's likewise impossible for zombies to walk with no blood pumping through their veins and no way for them to move huge distances with no source of energy, nor does it make sense that they could run, carry heavy weapons, be strong enough to strangle people, but are somehow incapable of swimming. Nor do the aerodynamics of the living dragons make a whole lot ...
Magic is not the answer (in this case)
Magic is not the correct answer here, in my opinion. There are many things about the dragons that can be answered by magic:
How Viserion was born from a petrified egg
How zombie Viserion was resurrected from a corpse
How Viserion's dragonfire is different from normal fire
How zombie Viserion's icefire works in the ...
No there is no such mention in neither books nor the show.
It is unlikely there would be any mention either as:
Dragons vary in their strength, agility and endurance so one definite answer is not possible.
GRRM deliberately refrains from explicitly stating anything like speed, time, climb rate etc.
When a fan asked how big is Westeros, his answer was:
A lot of the material and references you mention are part of the Dungeons and Dragons game source material.
In particular, Tales of the Sword Coast takes place in the Forgotten Realms setting, which is a campaign world designed by Ed Greenwood for his Dungeons and Dragons game, and which eventually became a licensed product that included source books, ...
Dragons are susceptible to physical injury, especially those involving sharp metal-pointed spears or arrows as well as injury from blunt trauma.
The 4th in the Dunk and Egg novella series "The Princess and the Queen" by GRRM contains a vivid depiction of the damage a dragon can receive:
Hundreds fled in terror from her flames … but hundreds more, drunk ...
Eärendil killed him at the end of the First Age. "Of the Voyage of Eärendil and the War of Wrath" from the Silmarillion has:
Before the rising of the sun Eärendil slew Ancalagon the Black, the mightiest of the dragon-host, and cast him from the sky; and he fell upon the towers of Thangorodrim, and they were broken in his ruin.
This is during the last ...
Their origin is not entirely known.
This source states:
Tolkien clearly wrote that dragons were bred by Morgoth but no one is
sure how. Some belief that dragons are embodied Maiar, others believe
they are simply beasts who were trained by Morgoth to speak and to
think, still others suggest they are "sparks" of Morgoth himself,
another theory is ...
Number of Dragons in Westeros
In Westeros Dragons first came with Targaryen invaders. There were three of those dragons:
Balerion the Black Dread
In reign of King Viserys I, twenty dragons were alive. Since records aren't kept for all hatchlings, we only have records of dragons which grew up a bit. Many hatchlings died in infancy and ...
In order to hatch a dragon in A Song of Ice and Fire, the eggs must be
heated to an incredible heat
Who said that? Dragon incubators do not exist in Planetos.
Hatching a dragon is not that simple.
All the accomplishments of the Dragon Lords were thanks to Blood magic. They possibly used blood magic to hatch dragons from ...
At the risk of stating the obvious: Dragons fly and breathe fire.
The largest bird of prey in our world is the Eurasian vulture, weighing up to 14 kg. Assuming the weight of a fully grown dragon is similar to an elephant, dragons weigh about 5500 kg, or nearly 400 times more than a vulture. The people of Westeros may not understand the details of ...
Probably Jeremy Thatcher, Dragon Hatcher, by Bruce Coville
Jeremy Thatcher knows a thing or two about raising animals-after all, his dad is a veterinarian. But after he leaves Mr. Elives' magic shop with a strange marbled egg, it soon becomes clear that this is one pet he wasn't prepared for! How is he supposed to keep a flame-breathing ...
Some real-world animals are thought to be able to go for a very long time without food, relatively speaking. For example, crocodiles can go over a year without eating and this page says it "is typical" for some snakes in the wild to go without food for 6 months.
If we assume that Smaug gorged himself after coming to Erebor and slowed his metabolism in the ...
As usual, Tolkien Gateway has the best compilation of info:
There were 4 named ones:
Glaurung — Father of Dragons, slain by Túrin Turambar. First of the Uruloki, the Fire-drakes of Angband. He had four legs and could breathe fire, but didn't have wings.
Ancalagon the Black — first and mightiest of the Winged-dragons, slain by Eärendil in the War of Wrath.
Sounds like Jeremy Thatcher Dragon Hatcher by Bruce Coville, the second book in the Magic Shop series.
It involves a boy of primary-school age obtaining a dragon egg from a magic shop.
Sixth-grader Jeremy Thatcher discovers a strange magic shop he has never seen before. He enters, and his life is changed forever. Buying what he thinks is a marble, he ...
You have to read the whole passage. Specifically:
... his enemies were on an island in deep water too deep and dark and cool for his liking.
Smaug could fly and would likely initially attack from the air in an assault on a target like Lake Town. However, he wasn't a machine. He would eventually tire from flying around or need to land for more precise ...
As Dawny33 speculated, and speculated correctly. It was fire.
This is confirmed in an interview by The Huffington Post with director of the episode "Dragon and the Wolf", Jeremy Podeswa, when asking the all important question "Was it Ice or Fire?". (Emphasis mine throughout)
“The way I looked at it was, when the sept burned down, that was green fire, and ...
