A COMPANION COLLECTION Ā· NOT THE MAINLINE FOURTH NOVEL
THE COLLECTION
A familiar trial, seen from new perspectives
Threshing Day is the latest book in the Fourth Wing universe: a companion collection in Rebecca Yarrosās Empyrean series, not the next mainline novel after Onyx Storm. Its thirteen stories revisit the dangerous day when rider candidates enter the valley and dragons decide whether to bond with them.
Violetās own Threshing is part of Fourth Wing. This collection widens the view to other characters and their dragons, adding context to their choices, histories, and bonds. Some stories follow the same day from different perspectives.
AT THE HEART OF THE STORIES
What the Threshing asks of each rider
01
Choice and cost
Becoming a rider means choosing under pressure, with fear, competition, and the risk of death close at hand.
02
Identity and growth
Family history, old wounds, ambition, and self-doubt shape how each candidate faces the valley. A dragonās choice can reveal who they are becoming.
03
Bond and fate
Riders do not tame dragons. A dragon chooses its rider, and that bond changes the riderās power, duties, relationships, and future.
STORY DETAILS & AUTHOR NOTES
What Threshing Day adds to the dragon lore
The collection makes parts of the bonding ritual more concrete, while leaving several signs open to interpretation.
01
A different kind of record
The opening note frames the stories as transcriptions by Basgiath Dragonkind professors Valin Kaori and Ellery Mynna. Business Insider reports that Yarros described this account as faithful and trustworthy, unlike the scribe-framed records in the main novels.
02
The bond can begin with a pull
Several cadets feel a physical tug that draws them toward a dragon. Blood also appears across the Threshings, but the collection does not settle why it happens.
03
A riderās needs may foreshadow a signet
Some candidates think about a need or wish just before bonding, and their later signets seem to echo it. Treat this as a story pattern to watch, not a confirmed rule for every rider.

Dragon lineages, hidden identities, and open theories
The story breakdown describes how similar dragon markings and rider-reported names can obscure a dragonās earlier bond. It connects that uncertainty to forbidden bonds involving a riderās direct family, which can create the possibility of multiple signets. It also unpacks how concealed ancestry affects what readers know about Xaden and Sgaeyl.
Business Insider also reads Garrickās and Bodhiās loyalty to Xaden as possible venin foreshadowing. That, along with predictions about missing family members or future romances, remains interpretationānot a confirmed answer from Yarros.
