Fatos conhecidos
A partir de agora, as origens dos ovos do dragão estão à altura da especulação. Primeiro temos como Marcus Swope diz:
"What are they?" she asked, her voice hushed and full of wonder.
"Dragon's eggs, from the Shadow Lands beyond Asshai," said Magister
Illyrio. "The eons have turned them to stone, yet still they burn
bright with beauty."
AGOT - Daenerys II
Então, Illyrio acredita ou foi informado pelo vendedor de que esses ovos são das Terras das Sombras, além de Asshai.
É bem possível que Illyrio esteja certo. Dragões afinal existiram em todo Essos (e mesmo Westeros) antes da ascensão de Valyria e há algumas teorias de que Shadowlands além de Asshai pode ter sido o lugar onde as origens dos Dragões se encontram (disputada por Valyrians e Qartheen).
In such fragments of Barth’s Unnatural History as remain, the septon
appears to have considered various legends examining the origins of
dragons and how they came to be controlled by the Valyrians.
The Valyrians themselves claimed that dragons sprang forth as the
children of the Fourteen Flames, while in Qarth the tales state that
there was once a second moon in the sky. One day this moon was scalded
by the sun and cracked like an egg, and a million dragons poured
forth.
In Asshai, the tales are many and confused, but certain texts—all impossibly ancient—claim that dragons first came from the Shadow, a
place where all of our learning fails us. These Asshai’i histories say
that a people so ancient they had no name first tamed dragons in the
Shadow and brought them to Valyria, teaching the Valyrians their arts
before departing from the annals.
Yet if men in the Shadow had tamed dragons first, why did they not
conquer as the Valyrians did? It seems likelier that the Valyrian tale
is the truest.
But there were dragons in Westeros, once, long before the Targaryens came, as our own legends and histories tell us. If dragons did first
spring from the Fourteen Flames, they must have been spread across
much of the known world before they were tamed. And, in fact, there is
evidence for this, as dragon bones have been found as far north as Ib,
and even in the jungles of Sothoryos. But the Valyrians harnessed
and subjugated them as no one else could.

Especulação
Com o recente lançamento de Fire & Sangue , acredito que encontramos a resposta para esta questão, embora não seja explicitamente mencionada.
Rei Jaehaerys Eu concedi Pedra do Dragão a sua irmã, a rainha-viúva Rhaena Targaryen, onde ela passou a morar com sua filha Aerea, sua cunhada (na verdade, sua amante secreta) Elissa Farman e outros cortesãos. Elissa queria navegar pelo mar do pôr-do-sol, mas não tinha a moeda para comprar o navio que ela tinha em mente. Ela pediu a Rhaena Targaryen para pagar a conta, mas Rhaena se recusou a fazê-lo. Elissa encontrou outro jeito. Havia ovos de Dragão no Targaryen e cada um deles era inestimável. Elissa roubou três ovos e se dirigiu para Bravos porque a cidade era famosa por navios de pesca.
Depois de não conseguir rastrear Elissa, Rhaena se empenhou em informar seu irmão, o rei, sobre o roubo. Jaehaerys ficou alarmado e ordenou que os agentes fossem enviados por toda Essos e oferecesse recompensas por qualquer notícia dos ovos do Dragão. Jaehaerys estava seriamente preocupado com o que aconteceria se os Ovos encontrassem seu caminho para Volantis e o sangue Velho da cidade conseguisse chocá-los. Não muito tempo atrás, foi preciso uma Aliança de Essos e Westeros para derrotar Volantis, que queria reviver o Império Valiriano, até mesmo Aegon, o Conquistador, participou de seu dragão. Ele decidiu que em qualquer notícia de Dragões chocando no Oriente, ele exigiria seu retorno. Se aquele país não os devolvesse, Jaehaerys declararia guerra.
Elissa Farman departed for Driftmark the next morning. From there she took ship across the narrow sea to Pentos. Thereafter she made her
way overland to Braavos, whose shipwrights were far famed, but
Rhaena Targaryen and Princess Aerea had no notion of her final
destination. The queen believed she had gone no farther than
Driftmark. Lady Elissa had good reason for wanting more distance
between her and the queen, however. A fortnight after her departure,
Ser Merrell Bullock, still commander of the castle garrison, brought
three terrified grooms and the keeper of the dragon yard into Rhaena’s
presence. Three dragon eggs were missing, and days of searching had
not turned them up. After questioning every man who had access to
the dragons closely, Ser Merrell was convinced that Lady Elissa had
made off with them.
[...]
She sent men to Driftmark, only to learn that Lady Elissa had sailed
to Pentos. She sent men to Pentos, but there the trail went cold.
Only then did Rhaena Targaryen mount Dreamfyre to fly to the Red Keep
and inform her brother of what had transpired. “Elissa had no love for
dragons,” she told the king. “It was gold she wanted, gold to build a
ship. She will sell the eggs. They are worth—”
“—a fleet of ships.” Jaehaerys had received his sister in his solar,
with only Grand Maester Benifer present to bear witness to what was
said. “If those eggs should hatch, there will be another dragonlord
in the world, one not of our own house.”
“They may not hatch,” Benifer said. “Not away from Dragonstone. The
heat…it is known, some dragon eggs simply turn to stone.”
“Then some spicemonger in Pentos will find himself possessed of
three very costly stones,” Jaehaerys said. “Elsewise…the birth of
three young dragons is not a thing that can easily be kept secret.
Whoever has them will want to crow. We must have eyes and ears in
Pentos, Tyrosh, Myr, all the Free Cities. Offer rewards for any word
of dragons.”
“What do you mean to do?” his sister Rhaena asked him.
“What I must. What you must. Do not think to wash your hands of this,
sweet sister. You wanted Dragonstone and I gave it to you, and you
brought this woman there. This thief."
[...]
“Should the dragons turn up, anywhere from here to Yi Ti, we will
demand their return. They were stolen from us, they are ours by right.
If that demand should be denied, then we must needs go and get them.
Take them back if we can, kill them if not. No hatchlings can hope to
stand against Vermithor and Dreamfyre.”
[...]
Grand Maester Benifer said, “You are speaking of waging war across
thenarrow sea, Your Grace. The costs—”
“—must needs be borne. I will not allow Valyria to rise again. Imagine
what the triarchs of Volantis would do with dragons. Let us pray it
never comes to that.” With that His Grace ended the audience,
cautioning the others not to speak of the missing eggs. “No one must
know of this but we three.”
Fire and Blood: Birth, Death and Betrayal Under King Jaehaerys I
Elissa vendeu os Ovos para o Sealord de Bravos e conseguiu sua nave.
She took on a bastard name of her own devising, calling herself Alys
Westhill. Under that name, she secured an audience with the Sealord of
Braavos. The Sealord’s menagerie was far famed, and he was glad to buy
the dragon eggs. The gold she received in return she entrusted to the
Iron Bank, and used it to finance the building of the Sun Chaser, the
ship she had dreamed of for many a year.

Birth, Death and Betrayal Under King Jaehaerys I
Enquanto isso, em Westeros, devido a outra emergência, a busca pelos dragões foi cancelada e os agentes receberam novas tarefas. Mas, por fim, a palavra chegou ao Red Keep devido ao erro de Elissa Farman em ligar para o porto na Cidade Velha. Dado o design único do navio, Jaehaerys tinha certeza de que Bravos comprara os ovos e construíra o navio.
Jaehaerys enviou sua Mão Septon Barth para Bravos para negociar o retorno e ameaçar Braavos com total destruição se eles recusassem. O Sealord contra-atacou com sua própria ameaça (que apesar de Bravos não poder lutar contra o Trono de Ferro, ele enviaria os Homens sem rosto após os Targaryens para vingar sua cidade) e conseguiu um acordo que, enquanto os Dragões não chocassem, Jaehaerys deixaria mantenha os ovos. Se os Dragões chocassem, o Sealord iria devolvê-los. Em troca da compreensão do rei, Bravos faria com que o banco de ferro renunciasse a todos os empréstimos do trono de ferro. Como o trono estava se afogando em dívidas dos reinos e guerras dos reis Aenys e Maegor, Barth concordou. A questão nunca surgiu novamente, dado que nenhum dragão eclodiu e presumivelmente eles apenas assumiram que os ovos deviam ter se transformado em pedra.
Dois séculos depois, três ovos de pedra encontram seu caminho para um "picoshi spicemonger" Illyrio Mopatis, exatamente como Jaehaerys havia dito. Esses são provavelmente os três ovos que foram roubados da Pedra do Dragão e sem o conhecimento de Daenerys, eles eram sua conexão com o legado de seus ancestrais e suas raízes o tempo todo.
