What is Threshing Day in the Fourth Wing universe?

Threshing Day is a September 29, 2026 companion book with 13 character stories set in Rebecca Yarros' Empyrean saga. It bridges Onyx Storm and future mainline entries while feeding the Dragonkind interactive experience.

Do I need to read Onyx Storm before Threshing Day?

Yes. Official reading order is Fourth Wing, Iron Flame, Onyx Storm, then Threshing Day. Spoilers for Onyx Storm and earlier books apply throughout.

Is Threshing Day Fourth Wing the same as the Dragonkind game?

No. The book is print/digital prose. Dragonkind at dragonkind.com is a separate browser survival sim launched October 1, 2026. Both share lore and marketing but serve different intents.
