Heavy is the head that wears the crown.

In the new Game of Thrones prequel series House of the Dragon, King Viserys I Targaryen (Paddy Considine) sits atop the Iron Throne, but with it comes heavy duties and harsh challenges.

As the King strives for a male heir, he must also contend with his roguish brother Prince Daemon Targaryen (Matt Smith) vying for the crown himself, along with the other schemers at court.

However, could Viserys’s ideal heir actually be in his only legitimate child, Princess Rhaenyra Targaryen (Milly Alcock, Emma D’Arcy)?

In the first episode, titled The Heirs of the Dragon, Viserys shares some secrets of ruling with Rhaenyra.

So, just what was Aegon’s Dream, the Song of Ice and Fire, and the Prince That Was Promised in House of the Dragon?

What is Aegon’s Dream and the Song of Ice and Fire?

Towards the end of the first episode of House of the Dragon, King Viserys tells Princess Rhaenyra how it was a dream that stirred King Aegon I Targaryen to cross over Blackwater Bay from the island of Dragonstone to conquer the Seven Kingdoms of Westeros.

It was in this dream that Aegon saw a future where an endless winter will come down from the North with a terrible darkness riding within it to destroy the world of men, ending all life in this world.

Viserys notes, however, that a Targaryen must be leading Westeros – either a man or woman – to be the Prince Who Was Promised to defend the land of the living against this evil.

The dream was called The Song of Ice and Fire, and Viserys notes that Targaryen monarchs since Aegon have passed on the knowledge of this prophecy to their successors – and now, Viserys is telling Rhaenyra as he plans to make her his heir.

Of course, this prophecy actually fortells the events of Game of Thrones and the Army of the Dead that comes commanded by the White Walkers and the Night King.

In Game of Thrones season 8 episode 3 (The Long Night), it is a union of the realms of men, led by the Targaryen descendants Queen Daenerys Targaryen and King Jon Snow (Aegon Targaryen), who are able to defeat the army and save Westeros, albeit with Arya Stark delivering the killer blow to the Night King.
