Anatomy: the daggertail
A daggertail keeps the edge of a swordtail and concentrates it into a point. The books describe the result as capable of eviscerating with a single flick, which makes it the fastest killing tail of the five weapon forms. There is no windup and no weight behind it. There is a movement, and then there is a body.
Put that tail on a blue, and the pairing earns its reputation twice over. Blue is called the most ruthless of the six colours, so the tail that kills quickest sits on the colour least likely to hold back.
Sgaeyl is the dragon the books use to demonstrate it. She is the most powerful blue in active service, and her record is the reason the phrase blue daggertail carries weight in a conversation.
Where the record stops
Sgaeyl has no established full name. Dragons reveal their full name only to their own rider, and reachable material does not give hers, so this record holds the field open. That is not an oversight. It is the honest state of the evidence.
Her age is not established either, beyond the fact that one previous rider died fifty years before she chose again. The books do not put a number on her, and this page will not invent one.
Everything else on this page is drawn from what the books state: golden eyes, blue horns, blue daggertail, the most powerful blue in service, a mate, a rider, and a previous rider lost long before the story opens.

The bond record
A rider lost
Sgaeyl's previous rider died fifty years before the events of Fourth Wing. Each subsequent bond a dragon forms is described as stronger than the last.
Xaden Riorson
Sgaeyl chooses Xaden Riorson, the son of the executed Duke Fen Riorson and the leader of the marked ones. The choice is treated as deliberate rather than convenient.
The mating
Sgaeyl is mated to Tairn. Mated pairs are the strongest bond in the world and cannot be separated for extended periods, roughly three days, without their health deteriorating.
The consequence
Because their dragons are mated, Sgaeyl's rider and Tairn's rider are posted together. A dragon decision made before either rider met the other ends up dictating where they serve.
What Sgaeyl reads as in our game
In the bonding engine on this site, blue leans on loyalty and instinct: a run that keeps faith with the people it entered the valley with, and trusts the read it cannot explain, drifts toward blue. The tail rolls separately, so a blue daggertail is rare rather than guaranteed.
That is design, not canon. The books describe a dragon choosing a rider for reasons of its own, with no scorekeeping anywhere in the text.
The rider and the mate, stated plainly
Spoilers: Fourth Wing
This section contains material from later in the series.
Sgaeyl is bonded to Xaden Riorson and mated to Tairn, who is bonded to Violet Sorrengail. The mating predates both bonds, and it is the reason the two riders cannot be sent to different posts for long.
Her previous rider is the reason the books treat her choice of Xaden as significant. A dragon that waited fifty years does not choose casually.
Sgaeyl at Xaden's Threshing
Spoilers: Threshing Day
This section contains material from later in the series.
The collection gives an account of Xaden Riorson Threshing: he led the first ten marked children into the quadrant, was ambushed, and killed Prince Alic Tauri Baran with a sword strike. Sgaeyl incinerated the bodies before she chose him, erasing the evidence of what had happened in the valley.
That sequence is community-reported detail from reader summaries rather than a quotation from the published text, and it is gated here for the same reason the collection is: it reveals what the main series only reports after the fact.

Yes, one who died fifty years before she chose again. Each bond a dragon forms is described as stronger than the last.
Blue leans on loyalty and instinct in our engine. That is site-game design. The books describe a dragon making a choice, not a scoring system.
