The Vaults of Terra series is Chris Wraight’s three-novel Inquisition saga set on Holy Terra itself. It follows Ordo Hereticus Inquisitor Erasmus Crowl and his acolyte Luce Spinoza as they uncover a conspiracy reaching the highest levels of Imperial power.
What the series is
Chris Wraight wrote the Vaults of Terra series for Black Library. It’s part of the Warhammer 40,000 universe and takes place on Terra, the heart of the Imperium, where the Emperor sits on the Golden Throne.
The story follows Inquisitor Erasmus Crowl and his acolyte Luce Spinoza as they investigate a plot that reaches the very top of Terra’s authority. Expect treason, shadowy catacombs beneath the Imperial Palace, and the byzantine politics of the Imperial Court.
The books and stories
Three main novels make up the series, supported by short stories and an audio drama. A special edition boxed set collecting all three novels was announced in November 2023, limited to 1,500 copies.
| Title | Type | Year |
|---|---|---|
| The Carrion Throne | Novel | 2017 |
| Argent | Short story | 2017 |
| Sanguine | Short story | 2017 |
| The Interrogation of Salvor Lermentov | Audio drama | 2018 |
| The Hollow Mountain | Novel | 2019 |
| The Dark City | Novel | 2022 |
| Okira | Short story | 2024 |
Why it matters
Most 40k stories take place on distant battlefields. The Vaults of Terra series does something different: it digs into Terra itself, the rotting heart of the Imperium, and shows how corruption and conspiracy work at the very centre of power.
It’s also a strong entry point for readers who like Inquisition stories, political intrigue, and detective-style investigations rather than pure warfare. The series connects to Wraight’s other Terra-set work, Watchers of the Throne, which covers the same era from a different angle.
The special edition collection
The Vaults of Terra Collection gathers The Carrion Throne, The Hollow Mountain, and The Dark City in leather-effect covers. Each book includes internal artwork, a black ribbon bookmark, an introduction by Wraight, and one bonus short story: Sanguine, Argent, and Okira respectively. It was limited to 1,500 copies.
