Daenerys estava basicamente inventando isso, mas há evidências de que ela pode ter atingido algo maior.
Para este fim, o nascimento dos dragões de Daenerys foi realmente mágico,
The birth of Dany's dragons was unique, magical, wonderous, a miracle. She is called The Unburnt because she walked into the flames and lived.

Agora, para um pouco mais de profundidade ...
Em primeiro lugar, devemos estabelecer que a magia funciona de forma misteriosa no mundo do gelo e do fogo, como explicado em um Q & A com GRRM,
Question 8 - Do you have rules worked out for magic?
Whole book is to his discretion as to how it works. He doesn't have a magic system specifically. Some authors do but too like D&D for him. He went back to Tolkien when he got into the book seriously. Thinks Tolkien is still the master. What you discover when you read Tolkien with eye to magic is there is very little magic. Gandalf is wizard - wise but he doesn't whisper a spell and slaughter an entire army. He thinks fantasy needs magic as a seasoning. Too much seasoning and you can overwelm the dish. Too much magic can ruin a fantasy. Magic has to be magic - something that violates law of nature. "Unknown" - published between the two World Wars writen by Campbell - a real rationalist with a particular brand of fantasy. Campbell treated magic as science. GRR enjoyed reading them but that approach to magic and the aproach in role playing games is...just science, not magic. Magic has to be more mysterious than that. He wants less Campbell and more Lovecraft. It has to be dark stuff we can't fully comprehend. Use it sparingly so it has impact.

OCTOCON Q&A
Ele faz isso de propósito para evitar se contradizer e não ter que lembrar de "regras",
Someone asked how, as a 'gardener' style of writer, George manages to set and stick to the "rules" of his fantasy world without contradicting what has gone before. George answered that he doesn't have to worry about contradicting his magical system because he's deliberately limited the magic and intentionally tries to keep it magical and mysterious, that the essence of magic is that it must be "wondrous and unexplainable". He doesn't like what other authors have done, which is to treat magic like a different kind of science with its own set rules.

Agora, jogue na história como pertence a Westeros. Os ovos de dragão foram conhecidos durante todo o reinado de Targaryen, mas nenhum deles eclodiu em algumas centenas de anos.
Nine mages crossed the sea to hatch Aegon the Third's cache of eggs. Baelor the Blessed prayed over his for half a year. Aegon the Fourth built dragons of wood and iron. Aerion Brightflame drank wildfire to transform himself. The mages failed, King Baelor's prayers went unanswered, the wooden dragons burned, and Prince Aerion died screaming.
A Storm of Swords, Davos V
E dentro da série, Melisandre tenta convencer Stannis a usar "sangue de reis" para acordar dragões de pedra em Pedra do Dragão. Este é o folclore do livro e está sendo para complementar a minha resposta, no entanto, o show não explora este enredo.
"Your brother's blood," Melisandre said. "A king's blood. Only a king's blood can wake the stone dragon."
Stannis ground his teeth. "I'll hear no more of this. The dragons are done. The Targaryens tried to bring them back half a dozen times. And made fools of themselves, or corpses.
A Storm of Swords - Davos IV
"I am a small man," Davos admitted, "so tell me why you need this boy Edric Storm to wake your great stone dragon, my lady." He was determined to say the boy's name as often as he could.
"Only death can pay for life, my lord. A great gift requires a great sacrifice."
A Storm of Swords - Davos V
Então, aqui temos um segundo personagem crendo (e provando com as três mortes das sanguessugas anteriores que estavam no show) em magia de sangue e "só a morte pode pagar pela vida".
Então, para fazer um círculo completo, Daenerys realmente não sabia o que estava fazendo, mas a partir de sua experiência com Mirri Maz Duur tropeçou em uma poderosa magia.
Para abordar seus outros pontos:
- She asks Rakharo to place the dragon eggs on the pyre seemingly because "They were not given to me to sell". A point to be considered is that in the future episodes she does several things that are much below this like selling her dragon to Kraznys, stealing items from Qarth, etc.
Ela não tinha nenhuma real intenção de vender seus dragões, pois é evidente que assim que Daenerys consegue controlar os Imaculados, ela imediatamente o imola.
Qarth, especificamente Xaro Xhoan Daxos, traiu Dany e roubou seus dragões. Uma vez, ela lida com ele, ela retorna o favor e rouba dele ... afinal ele não vai precisar mais.
- She gives a human sacrifice (Mirri Maz Duur) as required. A point to be considered here is that Mirri Maz Duur was most probably directly responsible for the death of Khal Drogo in that unhonourable way and the death of her child, and she only says "But it is not your screams I want. Only your life."?
É aí que entra em jogo a coincidência e "ela faz a magia conforme avança". Ela vê que a magia do sangue funcionou, mas não da maneira que Dany pretendia. Desde que Daenerys tem um pressentimento de que ela pode chocar os dragões (ela diz tanto para Jorah que ela sobreviverá à pira), mas também agora ver o poder da magia do sangue está seguindo "só a morte pode pagar pela vida".
