"We all want the same thing, brother-sergeant: to see Humanity reclaim not just the Jericho Reach, but our galaxy from our foes."
- —Adrielle Quist
Quist was first noted by Inquisitor Hezika Carmillus for her prodigious telepathic abilities. Her sharp, investigative mind distinguished her from her fellow acolytes, and during her time as an Interrogator she was one of a select few brought to the Tower of Brass when her mistress became Inquisitor of the Chamber at Watch Fortress Erioch.
Five short Terran years ago, Quist earned her rosette and became a full Inquisitor. She remains Carmillus' primary hand in the field. Quist has a deep fascination with alien technology that she keeps tightly concealed.
She is all too aware that many around her would brand her a Radical or a Traitor for her desire to see the Imperium match the technological advancement of alien species like the T'au. She is secretly one of the Crucible Resolviate's principal sources of xenos artefacts.
Quist would greatly like to find Deathwatch warriors who share her open mind about the path to humanity's advancement, as it would make procuring xenos items from their missions far less laborious.
In Watch Fortress Erioch, Inquisitor Quist resides in the Tower of Brass, the traditional home of the fortress' resident Inquisitor, keeping no guard outside as a show of her combat prowess.
Pass the door and up two spiraling flights of stairs can be found her audience chamber: a patterned marble floor with one wall made of a transparent plate of glassteel facing into the void. During Erioch's waking cycle, it faces the dim light from the system's cold, rising star.
As the chief field agent of Watch Fortress Erioch's Inquisitor of the Chamber, Inquisitor Quist spends far more time in the void than she does on Erioch. Her starship, the Angelus Invictus, is modest in size but highly customised. She provides Deathwatch battle-brothers a communal but sizable room for the journey.
Retractable metal slabs are built into the walls; their size is identical to the stone plinths of Erioch's cells, leaving little doubt that this room was made for the explicit purpose of transporting Kill-teams.
The ship has only a skeleton crew; whatever cadre the Inquisitor has, they are obviously out upon their own missions. Other than a few servitors and a decrepit cherub that rarely shifts from its perch in the galley, the living crew is limited to a pilot, Navigator Saminal Modar, and Nihl Zee, a Vindicare Assassin.
Of the Inquisitors of the Ordo Xenos who frequent the halls of Watch Fortress Erioch, none are more diligent or zealous than Adrielle Quist.
Quist has directed a number of Deathwatch missions into and beyond the Black Reef, often including instructions to retrieve particular xenos artefacts of interest to her and certain magi of the Adeptus Mechanicus.
However, the Inquisitor is also well-aware of her true duties to the Imperium, and many dire threats to the progress of the Achilus Crusade have been exposed and halted thanks to her efforts.
She has been known to personally accompany a Deathwatch Kill-team from time to time, particularly if the current mission is important to her own interests or those of Inquisitor Carmillus, her nominal superior.
