I'm leaning now towards the opinion that Denaerys should end up on the Iron Throne, but not until after she is dead. Jon should place her corpse there and build a funeral pyre around it. The throne should be melted down as she is cremated. Jon should let each of the Seven Kingdoms fend for themselves as he goes to join Ghost and the Free Folk beyond the wall.
They're probably not "full grown" yet.
I haven't read Fire and Blood. Is it supposed to be "neutral and "reliable" or is it in-universe propaganda that might portray dragons as tougher than they actually are ?
It is presented as the work of a Maester who seems quite favorable towards the Targaryens, especially King Jaehaerys I the Conciliator.
Something definitely seems off when he says that Jaehaerys was universally hailed as the only possible true heir to the throne, but then later mentions in passing that nearly half of the lords in the Seven Kingdoms referred to his older sister as their Queen and refused to pay any taxes to Kings Landing for many years.
He seems to think that most powerful woman were either silly girls ruled by their emotions, or wicked witches.
He also struggles to balance the fact that the king he admires over everyone else trusted Septon Barth above all others, with the fact that he seems to hate every one of Barth's heterodox ideas (like the theory that dragons are sequential hermaphrodites, rather than it just being hard to peek in their cloacas to check their sex before they lay eggs, or that the prince who was promised could be a woman).
He does not seem very fond of Aegon III, but mostly seems to view him as a poorly advised victim of the tragedies of the Dance of the Dragons, a civil war he would rather refer to as the Dying of the Dragons. No one in that war is presented well. Dragons cause a lot of problems, especially when both sides of a war has them, but the Maester seems to wish that they were still around to back the power of the Iron Throne.
Maybe having book Euron (afaik) would make some sense as the final antagonist, but show Euron is just a joke :/
If book Euron had shot Rhaegal he would have been guided to to so by a Shade-of-the-Evening-induced prophetic dream, and a Kracken would have risen out of the waves to devour the dragon as soon as he hit the waters.
Book Euron is an evil sorcerer wearing a full suit of Valyrian steel plate armor (something no Targaryen has ever been able to afford) he claims to have personally plundered from the smoking ruins of Valyria itself, and he plans to use mass human sacrifice (including priests of every deity known to man) to empower a dark ritual meant to transform himself into a god. He raped all of his younger brothers and their wives, cuts the tongues out of all his subordinates, yet is generous with his booty and keeps no wealth for himself. He has one black eye, one red eye, and lips permanently stained dark blue from drinking the Warlock's wine.
Fortunately the Baratheons are related to the Targaryens through marriage which is why Robert could become king after Aeris and Rhaeger were killed.
"Through marriage?" They are related by blood.
Robert's father was Steffon Baratheon, whose mother was Princess Rhaelle Targaryen, who was the youngest child of King Aegon V Targaryen.
Steffon was not the first Baratheon Lord to have a Targaryen mother either. Boremund Baratheon was the son of Rogar Baratheon and the Dowager Queen Alyssa Velaryon, the widow of Aenys I Targaryen and mother of King Jaehaerys. House Velaryon and Targaryen intermarried so often they might as well be considered the same house. Aegon the Conqueror himself had a Velaryon mother.
Also, the house was founded by a man widely believed to be Aegon the Conqueror's bastard brother.
