In the recent turmoil of House of the Dragon, King Aegon II Targaryen finds himself in a perilous situation. After a brutal battle at Rook’s Rest, both he and his dragon Sunfyre are left gravely injured. This puts the Greens at a significant disadvantage, as Sunfyre was one of their key assets in the ongoing dragon warfare. The Greens now face a harsh reality: their dragonpower is critically diminished, especially when compared to Rhaenyra's more numerous dragons.
Dreamfyre stands as the only viable replacement for Sunfyre. Bonded to Queen Helaena Targaryen, Dreamfyre is one of the oldest and most powerful dragons remaining on Team Green’s side. Hatched during the reign of King Aegon I Targaryen, Dreamfyre has a long history of fierce loyalty and formidable power. Before Helaena, Dreamfyre was ridden by Rhaena Targaryen, who flew her frequently, showcasing her might and valor.
Despite her strength, Dreamfyre has remained mostly in the Dragonpit at King’s Landing.
One major hurdle is Helaena Targaryen herself. In George R.R. Martin’s Fire & Blood, it’s noted that Helaena never rides Dreamfyre during the Targaryen Civil War, known as the Dance of the Dragons. While she has the bond and experience, Helaena lacks the will or opportunity to ride Dreamfyre in battle.
The dragons can only bond with one rider at a time, making it impossible for the Greens to assign another Targaryen to Dreamfyre. Thus, Dreamfyre remains largely a dormant asset within the Dragonpit, unable to actively participate in the war efforts.
As the war intensifies, the fates of Sunfyre and Dreamfyre grow darker. Sunfyre, though initially surviving the Battle at Rook’s Rest, is left severely wounded. King Aegon and Sunfyre eventually retreat to Dragonstone, where Sunfyre meets his end after a fierce battle with Baela and her dragon Moondancer.
Dreamfyre’s end is equally tragic. Following Helaena’s death, Dreamfyre, sensing her rider’s demise, becomes agitated and breaks free from her chains in the Dragonpit. During the Storming of the Dragonpit, an enraged mob kills Dreamfyre.
With the loss of both Sunfyre and Dreamfyre, King Aegon’s dreams of dominance through dragonpower are shattered. Even attempts to hatch new dragon eggs to replace Sunfyre fail, leaving the Greens with a diminished and vulnerable position in the war against Rhaenyra. This bleak outcome underscores the precariousness of relying on powerful but finite dragon resources in a brutal and unforgiving civil war.
