What Is the Battle at Rooks Rest?

Cole and his close ally Prince Aemond, however, have a different plan.

Ser Criston orders his troops to maneuver northeast towards Rooks Rest, the seat of House Staunton.

Are you afraid, ser?

Worse, Im rational.

With apologies to Ser Gwaynes rationality, Rooks Rest is actually a strategically-sound target.

Of course, the arrival of King Aegon II on Sunfyre is an unwelcome surprise to Cole.

Martins source materialFire & Bloodconfirms it as well.

There are, however, some differences between the shows Battle at Rooks Rest and the books.

In the book, Ser Cristons host is much larger consisting of around 3,000 men.

Did Rhaenys Die?

Like herFire & Bloodcounterpart, Rhaenys perishes at the Battle at Rooks Rest alongside her dragon Meleys.

The successful killing of both a dragon and a dragonrider marks one of the wars first big victories.

Believe it or not, they will not heed this lesson.

Did King Aegon II Die?

And now hes dead… or is he?

Aemond was imprecise (deliberately so) in where he had Vhagar aim her dragon fire during the battle.

Sunfyres wing is severely damaged and he tumbles out of the sky, Aegon in tow.

Aegon is probably alive…albeit barely.

This is consistent with the storyline as presented inFire & Blood.

There Aegon suffers devastating injuries and burns during the battle of Rooks Rest.

In his absence, Aemond steps up as Prince Regent and Protector of the Realm.

They say history doesnt repeat itself but it does rhyme.
