Inquisitor Severnius lead a Deathwatch Kill-Team (including Brother Artemis) to Tarrenhorst, where they soon discovered the population had been psychically enslaved by the Enslavers. The Enslavers used their powers on the team and managed to enslave several Space Marines before Severnius managed to raise a psychic shield. Under fire from the population and former comrades, they retreated to a small temple dedicated to the Emperor. There they fought the Enslavers puppets for six days, before they were able contact their ship in orbit and a Thunderhawk was dispatched to retrieve them. Before the Thunderhawk arrived a weakened Severnius was killed by an enslaved Space Marine, leaving command to Brother Artemis; gathering the Inquisitor's body, the Kill-Team boarded the Thunderhawk and returned to their ship. Once on board, Artemis ordered an Exterminatus launched on the doomed planet.
