Gregor Eisenhorn - History: Born in 198.M41, on DeKere's World, Gregor Eisenhorn was taken at an early age by the Black Ships and in time he became an Acolyte of Inquisitor Hapshant. He studied alongside fellow Inquisition apprentice Titus Endor and was elevated to the rank of full Inquisitor in 222.M41, at the incredibly young age of 24. His first successful persecution was that of the heretic Lemete Syre.Carving out a stable and competent career, Eisenhorn eventually found himself being drawn into events that would change the course of his life in the year 240.M41. During this year Eisenhorn succeeded in ending the menace of the mass-murderer Murdin Eyeclone, an investigation that is notable not only for bringing Godwyn Fischig and Alizebeth Bequin into his employ as Acolytes, but also for setting him in pursuit of both Pontius Glaw and the Necroteuch.Following leads from the Eyeclone investigation, Eisenhorn became tangled up with a heretical cabal on the world of Gudrun, and in fact was briefly captured and tortured by one of its members, Gorgone Locke. The cabal was eventually broken by a full Inquisitorial purge led by Inquisitor Voke. Eisenhorn was able to recover a device known as the Pontius from the cabal, and it later transpired that this device held the encoded brain-engrams of the infamous and long-dead Heretic Pontius Glaw; one of the cabal's schemes had involved arranging his resurrection.Eisenhorn held Pontius Glaw captive and interrogated him regularly, before finally choosing to have the Pontius device incarcerated by Magos Bure of the Adeptus Mechanicus. This decision would ultimately have a profound effect on Eisenhorn's future.Following up further leads from the cabal purge led Eisenhorn into one of his most famous investigations; the affair of the Necroteuch -- a tome of Chaos knowledge. Eisenhorn tracked the survivors of the heretical Gudrun cabal to a colony world inhabited by the xenos Saruthi. The Saruthi had come into the possession of a copy of the Necroteuch, and had translated it into their own language, creating two versions of this powerful Chaos tome and a translating tool.The human Necroteuch tome written in High Gothic was quickly found and destroyed by Eisenhorn himself. Some Radical Inquisitors deemed this a heretical act, and damned Eisenhorn for it. However, the majority of the local Inquisitorial conclave, which was dominated by Puritans, supported Eisenhorn's decision to burn the tome, outvoting the Radicals.Eisenhorn was therefore spared from censure and was in fact instrumental in planning a raid on the Saruthi homeworld during which the remaining tainted items were destroyed. It was during this attack that Eisenhorn also first met Cherubael, a powerful Daemonhost who would plague Eisenhorn and the Imperium in later endeavours.The following year, 241.M41, Eisenhorn investigated the apparent ritual murders on the world of Sameter, at first believing the killings to be the work of some Chaos Cult. Soon, however, it was revealed that the culprits were actually ex-soldiers of the Astra Militarum. These former soldiers of the Sameter 9th Infantry Regiment had been driven mad by the horrors they had faced in war, and were ritually killing regular citizens.Backed up by the Arbitrators of the local Adeptus Arbites, Eisenhorn managed to corner and eliminate the fanatics in an abandoned and decaying building. During the resultant firefight, Eisenhorn lost his left hand to an experienced former-sharpshooter. He was offered a bionic prosthetic but declined, making do with a fused stump until he could have a vat-grown hand grafted on two years later.In 312.M41, Eisenhorn's best friend and Acolyte, Midas Betancore, was killed by the Heretic Fayde Thuring during an investigation. Thuring escaped, and Eisenhorn promised to keep a watchful eye on Midas' infant daughter, Medea. Years later, when she came of age, she would follow the path of her father and join the retinue of Inquisitor Eisenhorn as his pilot.Twenty-six Terran years later, in 338.M41, Eisenhorn began the investigation that he would become most famous for across the Imperium; the elimination of the Heretic Inquisitor Quixos. The investigation took place in the aftermath of the disaster of the Thracian Primaris Triumph (where Eisenhorn's Interrogator, Gideon Ravenor, was horrifically injured), an atrocity that appeared to have been engineered to free several Alpha Plus-class rogue psykers from Imperial detention.Eisenhorn's investigation took him to the world of Eechan, where, posing as mutants, he and his team discovered that there was Inquisitorial collusion in the scheme that had freed the rogue psykers. Inquisitor Lyko was discovered in the company of the Daemonhost Cherubael. Taken aback by the reappearance of Cherubael, Eisenhorn focused his investigations upon the creature. This led him to the Fortress World of Cadia, where he discovered another Daemonhost, Prophaniti, and ties between these Daemonhosts and the missing Radical Inquisitor Quixos.However, Eisenhorn's investigation was sidelined for some time by his arrest by Inquisitor Osma for allegedly consorting with daemons. Escaping, he was declared outcast by the Inquisition and forced to operate as a rogue for the remainder of the investigation. Eisenhorn sojourned with his Adeptus Mechanicus associate Magos Bure on the world of Cinchare for some time, where he conferred with his prisoner, Pontius Glaw. During this period, he defeated a Chaos Cult that existed on the world and gained master-crafted Force Weapons.Eisenhorn next assembled a small strike group of three other Inquisitors, and acting in concert with them, tracked down and confronted the Renegade Inquisitor Quixos. Eisenhorn himself was the one who killed Quixos, recovered his heretical book, the Malus Codicium, and banished both Prophaniti and Cherubael to the Warp. Eisenhorn was cleared of all charges against him at the conclusion of the investigation.In 345.M41, Eisenhorn succeeded in secretly summoning the daemon Cherubael and trapping him in the physical universe for interrogation and study. In 355.M41 he dealt with a minor Warp incursion of daemons on Gudrun.It was in the year 386.M41 that Eisenhorn was able to avenge the death of Midas Betancore, but it came at considerable cost. Killing the Heretic Fayde Thuring cost him the lives of several associates, placed Bequin into a coma, resulted in the destruction of his personal starship, his gun-cutter, and forced him to use the daemon Cherubael as an ally. To control Cherubael, Eisenhorn sacrificed the naïve Puritan Inquisitor Bastian Verveuk in an improvised Chaos ritual. This foul misdeed was an important step on Eisenhorns' road to damnation.Shortly afterwards, Eisenhorn was the victim of a carefully planned attack orchestrated by Pontius Glaw, who had escaped the Inquisition's captivity and decided to punish and torment his captors. Almost every facet of Eisenhorn's life was brought crashing down around him, including his career, as he was once again declared an outcast by Inquisitors Osma and Heldane.His organisation shattered, his own body broken and much of his retinue dead, Eisenhorn was eventually able to call on the aid of his former pupil, Gideon Ravenor, who was now a full Inquisitor. With Ravenor's assistance, Eisenhorn was able to track Pontius down and eliminate him for good. However, the Pontius Affair did more than deplete Eisenhorn's physical resources, it also finally broke down his resistance to employing Radical methods of fighting Chaos and the Imperium's other enemies -- he began to travel with Cherubael as his constant companion.Eisenhorn largely dropped out of sight after the Pontius Affair, despite his outcast status apparently being rescinded once again by the Inquisition. He has reappeared for only brief moments in the years following, to recruit new Acolytes or confer with past associates, such as warning Gideon Ravenor about the intentions of the Chaos Cult known as the Divine Fratery. Later members of the cult discussed Eisenhorn and suggested that he may have been killed fighting their followers, as he was inside a building that they bombed and Eisenhorn subsequently vanished from their psychic foresight. The truth of his death can be disputed.
