Threshing Day

The Empyrean #3.5

by Rebecca Yarros

Welcome to Threshing Day, the brutal, high-stakes trial where would-be riders at Basgiath War College fight to earn the bond of a dragon or die trying. Amid ruthless competition and dragon fire, these thirteen cadets must survive a battlefield where desperate rivals will do anything to gain an advantage and dragons decide one’s ultimate fate―and where a single choice can forge a rider…or destroy them.

Xaden Riorson, the powerful leader. Rhiannon Matthias, the clever friend. Dain Aetos, the dutiful rule-follower. Liam Mairi, the kindhearted protector. Ridoc Gamlyn, the jokester. Sawyer Henrick, the underdog. Garrick Tavis, the dependable aide. Imogen Cardulo, the impulsive fighter. Bodhi Durran, the second-in-command. Mira Sorrengail, the fearless rider. Brennan Sorrengail, the brilliant tactician. Aaric Graycastle, the restless royal. Sloane Mairi, the determined sister.

On Threshing Day, there’s only one rule: don’t die.

Genres: Fantasy, Romantasy, Dragons, Romance, Fiction, Fantasy Romance, Adult

224 pages, Hardcover

Expected publication September 29, 2026

Did I expect something entirely different? Yes. Does this feel like a total cash grab? Yes. BUT WILL I STILL READ THIS JUST FOR RIDOC'S POV?? ABSOLUTELY 🙌🏻
Also, if she will add Liam's story, I will sue for emotional abuse.

THRESHING DAY?!?!!
we're getting to see xaden bond sgaeyl??? excuse me???
i'm already obsessed💋💋

[Grace Btrs (Catching Up!! - semi ia-work)]

IT'S 13 STORIES FROM THRESHING DAY
ahhhhhhhhh
Okay my guesses:
1- Xaden and Sgaeyl
2- Ridoc and Aotrom
3- LIAMMMMM (fuck break my heart) and Deigh
4- Tairn and Naolin (hear me out!!!)
5- Lilith and Aimsir
6- Dain and Cath
7- Mira and Teine
8- Aaric and Molvic
9- Imogen and Feirge
10- Garrick and Chradh
11- Brennan and Marbh
12- Rhi and Feirge
13- Sloane and Thoirt
No I don't remember names of all dragons, I searched some of them up :p

She did say beloved characters, so not Baide and Barlow
I would be down for Codagh's story tho...

What are your guesses?


--
WHATEVER THIS IS, I AM EATING IT UP. Crumbs, dust, and all.

Okay also so
Since this is not listed in the Empyrean Series thread, but it's added on RY profile alone (like a stabdalone would be)
Which leads me to believe it is not a novella about the main characters
It's probably some world lore like the Fables or the codex or an extended glossary or the guide to dragons or ALL OF THEM COMBINED
