The civil war tearing Westeros apart is shifting toward the south, bringing Daeron Targaryen Tessarion into the center of the conflict. While King’s Landing, Harrenhal, and the Gullet dominated earlier stages of the Dance of the Dragons, the war in the Reach now holds the fate of the Iron Throne. The introduction of Prince Daeron Targaryen and his magnificent dragon Tessarion gives the Greens their most dangerous offensive weapon.
For two seasons, viewers wondered when King Viserys and Queen Alicent’s fourth child would appear on screen. As explored in our deep dive into the House of the Dragon finale and Rhaenyra’s dark turn, the Blacks secured four new dragonriders through the Sowing of the Seeds. However, the arrival of Daeron Targaryen and Tessarion shatters Queen Rhaenyra’s strategic air supremacy in the south.
Understanding the bond between Daeron Targaryen and Tessarion is crucial for predicting the bloody clashes ahead in the Reach.
Who Is Prince Daeron Targaryen?
Prince Daeron Targaryen is the youngest son of King Viserys I Targaryen and Queen Alicent Hightower. Unlike his volatile older brothers, Aegon II and Aemond One-Eye, Daeron grew up far away from the toxic court politics of the Red Keep.
At a young age, Daeron was sent to Oldtown to serve as a cupbearer and squire to his mother’s uncle, Lord Ormund Hightower. Growing up in the shadow of the Hightower and the Citadel shaped Daeron into a courteous, thoughtful, and dutiful prince. In George R.R. Martin’s source text, Fire & Blood, archmaesters describe Daeron as the gentlest of Alicent’s sons, quick to learn and beloved by common soldiers and noble lords alike.
Yet gentle manners do not make him harmless. When war erupted following King Viserys’s death, Daeron took up his sword without hesitation to defend his family’s royal claim.
Tessarion, the Blue Queen: The Greens’ Deadliest Asset
Every Targaryen prince needs a mount, and the partnership between Daeron Targaryen Tessarion stands out among the dragons of the Dance.
Tessarion, famously known as the “Blue Queen,” is celebrated as one of the most stunning beasts in Targaryen history. Her scales shimmer with dark cobalt blue, while her belly scales, claws, and horns glisten like beaten copper. Her dragonflame burns with a distinct, searing cobalt color that illuminates the night sky.

Although Tessarion is younger and smaller than ancient behemoths like Vhagar or Vermithor, her compact size gives her unmatched aerial agility. When paired with the disciplined courage of Prince Daeron, the Blue Queen becomes an evasive, lethal hunter capable of outmaneuvering much larger opponents.

The Battle of the Honeywine: How Daeron Targaryen Tessarion Saves the Greens
The moment that establishes Daeron Targaryen Tessarion as a military legend is the Battle of the Honeywine.
Lord Ormund Hightower’s southern host found itself completely trapped between two Black armies along the banks of the Honeywine River. With Lord Thaddeus Rowan and Tom Flowers pressing from the north and Ser Alan Beesbury attacking from behind, the Hightower army faced absolute slaughter.
Just as the Green battle lines began to buckle, a shadow fell across the river. Prince Daeron and Tessarion swept out of the clouds, unleashing torrents of cobalt fire across the Black forces.
- Tessarion’s blue flame shattered the encirclement within minutes.
- Black foot soldiers broke formation and fled into the river.
- Enemy commanders were burned or captured on the field.
Following this miraculous victory, Lord Ormund Hightower knighted the young prince with the ancestral Valyrian steel blade Vigilance, dubbing him “Daeron the Daring.” The victory at the Honeywine reversed Green fortunes across the entire southern theater.
Why Daeron Targaryen and Tessarion Counter Rhaenyra’s Dragonseeds
The sudden rise of Daeron Targaryen Tessarion creates a massive tactical headache for Queen Rhaenyra Targaryen in King’s Landing.
With Aemond flying north to torch the Riverlands aboard Vhagar, the Greens lacked a dragon to secure the south. Daeron fills that exact void. As Ormund Hightower marches his host toward Bitterbridge and Tumbleton, towns fall before the Blue Queen’s wings.

To counter this advancing Green army, Rhaenyra must deploy her newly minted dragonseeds. As we detailed in our analysis of Ulf the White and Hugh Hammer, Rhaenyra sends the riders of Vermithor and Silverwing south to stop Daeron’s advance at Tumbleton. That fateful confrontation triggers one of the greatest betrayals in the history of Westeros.
The Legacy of Daeron Targaryen and the Blue Queen
The dynamic between Daeron Targaryen Tessarion reminds audiences that heroism and nobility exist on both sides of this civil war. Daeron was not driven by spite or bloodlust like his brothers; he fought out of genuine loyalty to his kin and realm.
As the series moves toward the catastrophic First and Second Battles of Tumbleton, Daeron and his Blue Queen will find themselves pushed to their physical and psychological limits. Their tragic arc illustrates the high cost of dragon warfare and the destructive weight of familial duty.
