“Colonel Kaori’s Field Guide to Dragonkind” is a referenced text within The Empyrean Series. It serves as an in-universe manual on dragon behavior, hierarchy, and rider-dragon dynamics. The book offers key insights into how dragons interact with humans, their social structures, and their unique traits.

Blue dragons descend from the extraordinary Gormfaileas line.
Known for their formidable size, they are the most ruthless,
especially in the case of the rare Blue Daggertail, whose knifelike
spikes at the tip of their tail can disembowel an enemy with one
flick.

Presentation Day is unlike any other. The air is ripe with
possibilities, and possibly the stench of sulfur from a dragon who
has been offended. Never look a red in the eye. Never back down
from a green. If you show trepidation to a brown…well, just don’t.

There is nothing quite as humbling, or as awe-inspiring, as
witnessing Threshing…for those who live through it anyway.

Though this officer considers himself to be an expert on all matters dragonkind, there is a great deal we don’t know about the way dragons govern themselves. There is a clear hierarchy among the most powerful, and deference is paid to elders, but I have not been able to discern how it is they make laws for themselves or at what point a dragon decided to bond only one rider, rather than go for better odds with two.

There is no stronger bond than that between two mated dragons. It goes beyond the depth of human love or adoration to a primal,
undeniable requirement for proximity. One cannot survive without the other.

It is the valley above Riorson House, heated by natural thermal
energy, that is its greatest asset. For there lie the original hatching
grounds of the Dubhmadinn Line, from which two of the greatest
dragons of our time—Codagh and Tairn—descend.

As dragons ferociously guard both their young and any information regarding their development, only four facts are known about the Dreamless Sleep. First, it is a critical time of rapid growth and development. Second, the duration varies from breed to breed.
Third, as the name suggests, it is dreamless, and fourth, they wake
up hungry.

Dragons do not answer to the whims of men.

By their third year, a rider must attain full and complete control
over their shields. Otherwise, in moments of extreme stress, they are susceptible to being not only influenced by their dragon’s emotions but controlled by them.

I’ll say one thing for dragonfire. It kills quickly.

Do not mistake a dragon’s bond for fealty. If you expect a dragon to choose their rider over the well-being of their own kind, prepare for two things: disappointment and death.

What we know about dragonkind is nothing compared to what we don’t.

No rider has ever survived the loss of their dragon. I can’t imagine wanting to.

The only thing more stubborn than a dragon is its rider.
