Gregor Eisenhorn

Gregor Eisenhorn was born on DeKere’s World in 198.M41 and entered the service of the Inquisition while still young. He trained under Inquisitor Hapshant alongside Titus Endor before becoming an Inquisitor of the Ordo Xenos at the age of twenty-four. Eisenhorn initially followed the Amalathian philosophy and believed that the Imperium should be preserved through careful intervention rather than reckless upheaval. His early investigations brought him into conflict with the House of Glaw and the alien Saruthi. During that campaign he destroyed the Necroteuch rather than allow its forbidden knowledge to survive and first encountered the daemonhost Cherubael.

Eisenhorn later pursued the radical Inquisitor Quixos after uncovering his involvement with daemonhosts and forbidden research. He was declared a rogue during the investigation but continued hunting Quixos with the help of his retinue and several allied Inquisitors. Eisenhorn eventually killed Quixos and recovered the Malus Codicium before being cleared of the charges against him. Despite once condemning such methods he secretly kept the book and later summoned Cherubael for interrogation. His willingness to use forbidden knowledge grew as threats became more extreme. The conflict with Pontius Glaw destroyed much of his organization and left Eisenhorn physically broken. He survived with permanent augmetic assistance and emerged far more willing to employ methods he had once considered unacceptable.

Eisenhorn continued hunting heretics and cults while operating increasingly outside conventional Inquisitorial authority. He bound Cherubael into his own service and eventually became regarded as a radical Xanthite by many of his former peers. His career repeatedly placed him under accusations of heresy even though his actions continued to target enemies of the Imperium. Gideon Ravenor eventually rose from Eisenhorn’s interrogator to become an Inquisitor in his own right. The two remained connected despite deep disagreements over Eisenhorn’s methods and the danger created by his growing reliance on forbidden powers.

Appearance: Gregor Eisenhorn has fair weathered peach skin and a tall broad athletic build. His eyes are dark brown. His short dark gray hair is brushed back from his forehead. Coarse gray stubble covers his jaw and chin.

He wears a heavy black and dark green long coat with broad armored shoulder plates and red lining. Gold trim runs along the coat edges and across the layered brown chest armor beneath it. Red cuffs cover his forearms. Purity seals and long parchment strips hang from his armor with dense written markings. A wide gray sash wraps his waist beneath a dark belt with a large gold buckle and several small chained ornaments.

His trousers are dark gray and tucked into heavy brown boots.

Personality: Eisenhorn is controlled and exceptionally strong-willed. He suppresses fear and grief because he believes hesitation can compromise an investigation or cost lives. His early career was defined by discipline and a strict rejection of corruption. Years of confronting enemies who possessed weapons beyond ordinary Imperial understanding gradually changed that certainty. Eisenhorn came to believe that forbidden tools could be used without surrendering to them if the wielder possessed enough resolve. He understands that this reasoning has carried him dangerously close to the same path followed by Inquisitors he once hunted.

Alizebeth Bequin became one of Eisenhorn’s closest companions despite her nature as a psychic blank making physical proximity painful for him. His feelings for her ran deeper than their professional relationship but her null presence made ordinary intimacy almost impossible. Gideon Ravenor began as Eisenhorn’s pupil and became one of the people whose judgment he respected most even after their beliefs diverged. Uber Aemos served as a trusted scholar while Godwyn Fischig gave Eisenhorn years of loyal service before becoming unable to accept how far his master had moved toward radicalism. Cherubael represents the clearest expression of Eisenhorn’s transformation. He once treated the daemonhost only as an abomination and later bound it into service because he believed its power could be turned against greater threats.

Eisenhorn is a powerful psyker whose greatest natural strength lies in telepathy and psychic compulsion. He can channel his will through his voice and force individuals or entire groups to obey direct commands. His psychic abilities are supported by extraordinary mental discipline that allows him to resist fear and hostile influence. Later experimentation by the Cognitae substantially increased his psychic strength. Eisenhorn is also an experienced investigator and interrogator with extensive knowledge of heresy and alien threats. He is a capable swordsman and has survived close combat against enemies far beyond ordinary human ability.

His best-known weapon is Barbarisater. The ancient Carthaen force sword once belonged to Arianhrod Esw Sweydyr before Eisenhorn inherited it after her loss. Magos Geard Bure later reinforced the weapon with pentagrammic wards that increased its effectiveness against daemonic enemies. Eisenhorn also received a runestaff from Bure for focusing his psychic abilities. After the injuries inflicted during the Pontius Glaw affair he required an augmetic support system around his lower body and later used a swordstick to assist his movement. His arsenal has changed throughout his career but his most dangerous weapons remain his psychic will and his willingness to use knowledge that other Inquisitors would destroy on sight.
