Owlcat shares the actors bringing Haymar, Epione, and others to life — with more to be announced soon
Nicosia, Cyprus (August 27th, 2026) — RPG powerhouse Owlcat Games has unveiled the first batch of talent voicing companions in the upcoming turn-based RPG Warhammer 40,000: Dark Heresy in a new trailer. The Imperium is brutal and unforgiving, and a talented cast was needed to fully realize a world where true justice is non-existent. The team at Owlcat delivers with the roster of Dark Heresy, welcoming Aaron Sinn as Haymar Devos, Jonathan Cox as Cogg, Brittany Chanel as Epione Spes, Stephen Spencer as Saro, Rhiannon Moushall as Ra’akhti, Chris Sharpes as Laarthyr Cairnareth, and Ian Russell as Servo-Ossuarium.
The introductory reveal for the cast of Dark Heresy announces a number of accomplished actors, both Owlcat veterans and newcomers, lending their talents to the upcoming CRPG: Emmy-nominated actor Aaron Sinn joins as Haymar Devos, native of the Imperium’s most infamous Death World Catachan and a former member of the Astra Militarum’s “Catachan Devils.” Notable for his roles in Sunny Side Down and Mouse: P.I. for Hire, Aaron brings over 15 years of experience to the world of Dark Heresy.
Jonathan Cox, known for his work on the previous Owlcat title Pathfinder: Wrath of the Righteous, voices Cogg. Jonathan’s portrayal of Cogg, an Ogryn with enhanced intelligence and fierce loyalty to the Imperium, showcases the character’s dogged determination.
Brittany Chanel (Psychology of Murder) brings her skills as Epione Spes, Officio Medicae who uses her cold, analytical mind to hunt down an elusive disease that has struck the sector capital of Scintilla.
Saro, the pyromantic psyker, is voiced by the talented Stephen Spencer, known for his work in titles like Lords of the Fallen. Though treated as an outcast by all other members of the Imperium, Saro carries his burden with his head held high and his gaze forever fixed upon the Exalted One.
Rhiannon Moushall, a fellow Owlcat veteran from her work in Warhammer 40,000: Rogue Trader, returns to the Warhammer universe as Ra’akhti, a Kroot scout. Declared an “Inedible” for transgressions against her tribe’s traditions, Ra’akhti is saved from a life of exile through a chance encounter with the player character, joining the acolyte’s retinue.
Chris Sharpes is another voice actor returning from his previous work on Rogue Trader as Pascal Haneumann, this time voicing Laarthyr Cairnareth, the Aeldari corsair. A Way Seeker and being of near unimaginable psychic power, Laarthyr’s true goals are steeped in mystery.
The final actor revealed in this first round is none other than Ian Russell, another fellow Owlcat veteran also known for his role as Rogue Trader’s probably most popular companion, Abelard Vesarian. This time Ian plays Servo-Ossuarium, the collection of servo skulls assigned to the player by The Inquisition to aid them in their task of rooting out heresy.
The initial Dark Heresy cast announcement already touts a stacked roster of talent, but the team at Owlcat still have more reveals planned. Be sure to keep an eye out to see who else was brought in to help bring the world of Dark Heresy to life.
Warhammer 40,000: Dark Heresy will launch on Windows PC via Steam, GOG, and Epic Games Store, and on consoles via PlayStation 5 and Xbox Series X|S.
