"Did someone say... G-g-g-g-GENESTEALTERS?!"Adrielle Quist is an Inquisitor of the Ordo Xenos. She went unnamed until The Shadow Over Immateriums.
TTS Canon Edit
Adrielle is completely single-minded, even for an inquisitor. She suspects genestealers to be behind every single plot, including the Emperor's message. She seems to be completely unaware of the existence of Chaos as well, assuming chaos cults to really be genestealer cults.
She first appears when Inquisitor Fyodor Karamazov calls together the Inquisition to investigate potential heresy on Holy Terra. From there she would go on to accompany Karamazov in 'questioning' the citizens of Terra, and in his Crusade to the Imperial palace, often appearing alongside Inquisitor Donklas of the Ordo Hereticus and Grand Master Elirush of the Ordo Mallaeus.
During the Inquisition's exile, she encountered Kairos Fateweaver while she was drunk, and asked him if he was a genestealer. Even though he had told her that one of his heads would tell the truth and the other would lie, she ignored him and attacked him when one of the heads said "yes".
Adrielle somehow managed to emerge from the Warp in time to save Bruce Norring from a genestealer cult the moment he identified them out loud. Still drunk, she managed to slay the entire cult including their patriarch, before returning to the Warp. When asked by Russ how she was able to jump back into realspace, she simply said "I dunno..."
During the battle at the Gate of Khaine, Adrielle, in a drunken stupor, was bombed into an unconcious state by daemon weaponry. Unsuprisingly she survived, whereupon awakening she was killed by a rather perturbed Skarbrand.
