Inquisitor Darkhammer is a Puritan of the dourest Unknown stripe, a zealot intent on scouring every scrap of alien life from the stars by the bluntest and most brutal methods possible. He has over thirty Exterminatus orders to his name, leading to horrified denunciations of Darkhammer as being more dangerous to humanity than the aliens he fights. Most recently he burned the world of Cavlock to deny a xenotech artefact to his rival Helynna Valeria, an action that finally earned him an Excommunicate Traitoris decree at her hand. Darkhammer pursues his calling undaunted, insisting that destroying the alien vindicates any number of human deaths.
