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

During the season finale of "House of the Dragon," Daemon goes to check on a dragon we haven't seen or heard about during the series before: Vermithor. The dragon is sometimes called the Bronze Fury in "Fire and Blood" because of his color. His original rider was King Jaehaerys — Viserys's grandfather — who was accepted by the dragon when he decided to claim the Iron Throne. After Jaehaerys died, the dragon made his home in the caverns at Dragonstone.

Daemon, worried about the war, goes to check on the dragon because he wants to find it a rider. In the books, they ultimately do, and a bastard named Hugh Hammer uses him as his mount.
