READING THE REFERENCE
The guide records black, blue, green, red, orange, brown, and irid dragons. A color entry identifies a den; it is separate from a dragon’s tail type.
The roster records swordtail, daggertail, clubtail, morningstartail, scorpiontail, and feathertail. These names describe tail classifications; the source does not establish a universal combat ranking.


THE CEREMONY THAT CHANGES EVERYTHING
At Basgiath War College, rider candidates enter the dangerous Threshing Valley and seek a dragon willing to bond with them. A dragon makes the choice; a cadet cannot tame or command one into a pact. The bond can channel a dragon’s power to a rider and shape the rider’s later abilities and responsibilities.
The danger is real in the books: a candidate who is not chosen may die in the valley. Threshing is a life-changing selection, not a safe graduation ceremony.
QUICK ANSWERS
The Empyrean is Rebecca Yarros’s fantasy series that begins with Fourth Wing. This reference also covers dragons and riders named in Iron Flame and Onyx Storm.
Threshing is the dangerous ceremony at Basgiath where dragon-rider candidates enter the valley and dragons choose whether to form a bond.
No. Dragonkind is an interactive experience inspired by the books. Its outcomes belong to the game experience and do not establish a character’s canonical dragon bond.
Search by a dragon’s English name, rider, den color, or tail type. Names stay in their original spelling so you can compare them with the books.
