Get to Know the Dragons of "House of the Dragon"

Arrax is the mount of Prince Lucerys. Luke bonded with the dragon when the beast was just a hatchling. In "Fire & Blood," he's described as five times smaller than Vhagar, which viewers got to see in the season one finale. Luke flies Arrax to carry a message to Storm's End, but runs into his uncle Aemond. Aemond challenges him and gives chase on Vhagar. The dragon kills Arrax and his rider, which is ultimately the first death in the Dance of Dragons.
