The questions
- What is Threshing Day?
The day each year when second-year riders at Basgiath War College enter the Vale and try to bond a dragon. It's the centerpiece of the Threshing Day short-story collection (2026). - How many dragons are there in the Fourth Wing series?
The official Dragonkind game works with a roster of 30 dragons to find and bond. - What is a dragon's signet?
The special ability a bonded pair can manifest — unique to each dragon-rider bond, and often dangerous to use. - What is a dragon's lineage?
The dragon's bloodline, printed on the bond card alongside its name, color, sex and age. - What happens if no dragon bonds you?
Historically, cadets who fail to bond don't become riders. In the official Dragonkind game, a burn sends you away to wait before you can try again. - What is the Empyrean series?
Rebecca Yarros's Fourth Wing series, of which the Threshing Day collection is a part. In-world, the Empyrean is the realm of dragons.
