Dreamfyre was a slender, apparently female, pale blue dragon with silver markings. Born after the Conquest on Peyredragon, she was ridden by Rhaena Targaryen, then by Helaena Targaryen.
She has laid at least two clutches of eggs.
Dreamfyre was given to Princess Rhaena Targaryen, daughter of the future King of the Seven Crowns Aenys I, when she was nine years old. She began riding him at the age of twelve, in the year 35.
At sixteen, having reached her majority, she travels the country on the back of her dragon. In the year 41, she went on a royal pilgrimage with her brother-husband, the prince of Peyredragon Aegon, but the events of the War of the Faith forced them to take refuge in Crakehall, then in Casterly Rock.
Taking advantage of the fact that the usurper Maegor I Targaryen is in Villevieille, the couple infiltrates King's Landing in order to retrieve Dreamfyre and Vif-Argent, their father's dragon, which becomes Aegon's mount.
They all fly to Castle Rosieres. After the death of Aegon and Quicksilver, Rhaena and Flintstaff go to Belle Ile, the fief of House Farman. They stay there for a few years.
In the year 47, Firebrand transports Rhaena back to King's Landing at the request of her uncle, Maegor I. Less than a year later, Rhaena escaped from the Red Keep by riding Flintknell to join her brother Jaehaerys, who had rebelled against their uncle.
She takes with her daughter Aerea and Feunoyr, the Valyrian steel sword of House Targaryen. Nine days after the mysterious death of Maegor I, Soneforth and Rhaena return to King's Landing, accompanied by Jaehaerys I on Vermithor and Alysanne on Silverwing.

After her brother's coronation in Villevieille, Rhaena accompanies the royal procession back to King's Landing.
But when she arrived in Highgarden, she left them with her dragon Safflower and returned to Belle Isle to live with House Farman. On the island, the dragon is a source of contention: while some pride themselves on its presence, many fear its voracity, and fears of a dragon invasion are heightened when Flintstaff lays a clutch.
In addition, Franklyn Farman, heir to Belle Isle, disapproves of his sister Elissa's escapades with Rhaena on the dragon's back. Dreamfyre also carries the queen's other friends, Samantha Castelfoyer and Alayne Royce.
When Franklyn Farman becomes lord and asks Rhaena to leave Belle Isle, Flintknife takes his mistress that night to Casterly Rock where she finds refuge.
However, the eggs laid by Flintstaff soon attract the Lannisters' covetousness, which decides Rhaena to leave. A few months later, Thief takes Rhaena to King's Landing to attend the official wedding of Jaehaerys I and Alysanne. After that, Rhaena moves to Peyredragon, where the three eggs laid by Soneforth hatch.
In the year 54, three more dragon eggs, probably laid by Sonnet, are stolen from Peyredragon by Elissa Farman. Rhaena, furious, rode to King's Landing on her dragon's back to warn her brother, King Jaehaerys I, who told her that no dragon born from one of these eggs could withstand the combined power of Soneforth and Vermithor.
The following year, after the disappearance of her daughter Aerea Targaryen, Rhaena travels the kingdom in search of her, and her dragon is seen in many places.
When she learns that her daughter has returned to King's Landing, Rhaena rushes back, but arrives too late: the girl is already dead. With the help of Thunderson, Rhaena scatters her ashes in the sky.
Princess Helaena Targaryen, daughter of King Viserys I Targaryen and his second wife Alicent Hightower, was not yet twelve years old when she first rode on Soneforth. In 120, Heleana is already considered a dragoness.
In the year 129, the succession conflict known as the Dance of the Dragons broke out. After the assassination of her son, Queen Helaena Targaryen goes mad; from that moment on, Dreamfyre is no longer useful for any battle, and cannot prevent the fall of King's Landing.
Some time later, Helaena commits suicide by jumping from the Red Keep. Upon her death, Firebrand, who remains in Fossedragon, suddenly rears up, breaks two of the chains holding her, and her screams shake the building.
During the Dance of the DragonsDuring the sacking of Fossedragon, Dreamfyre is the only dragon who manages to break her bonds. She flies off and kills more people than all the other dragons combined. A few crossbow bolts pierce her scales, but they don't incapacitate her.
Mad with rage and wounded in the eyes, she hits the great dome over Fossedragon in her flight, causing it to fall, and is crushed by the rubble along with many rioters.
