Kregor Thann

Senior Apothecary - Red Scorpions


Kregor Thann is a senior Apothecary of the Red Scorpions Space Marine Chapter. Thann is currently seconded by his Chapter to the Chamber Militant of the Ordo Xenos, known as the Deathwatch. He is currently serving his Vigil within the Jericho Reach at Watch Fortress Erioch, and is tasked with engineering various toxins that could help combat the growing Tyranid menace in that sector of space.


Kregor Thann is a veteran of countless war zones and a master of biological weaponry. Thann gained renown as the mastermind behind the geno-tailored toxins that made the Purging of Castillium possible, defeating the horrific Thazeme xenos when no other weapon could slay them. In the aftermath of the Purge, Commander Antir petitioned Lord High Commander Ortys to consider Thann for Deathwatch service. Thann arrived at Watch Fortress Erioch in 815.M41, and has served there ever since. Thann was not assigned to a Kill-team, but rather remains as part of Watch Commander Mordigael’s command staff, tasked with engineering a virus or toxin that could be used to combat the Tyranid menace. Like many Apothecaries in the Red Scorpions Chapter, Thann had served as a Sergeant as well as in his role as a medic, which is quite useful to less-experienced Kill-teams deployed to the Orpheus Salient of the Achilus Crusade. Thann’s duties have taken him across much of the Orpheus Salient, and he has served alongside a dozen Kill-teams in the prosecution of his duties, taking samples of various Tyranid flora and fauna, or testing recently developed concoctions in the field. To date, he has not successfully developed a substance that works for more than a single generation. The Tyranids are able to adapt, swiftly overcoming Thann’s creations, though his tests have still provided numerous opportunities for other Imperial forces to drive back the crippled swarms.

Thann has been operating towards the Spinward edge of the Orpheus Salient, pushing deep into the heart of the Tyranid advance. Thann continues to coordinate with each Kill-team that is operating deep behind enemy lines in order to gather samples and deploy newly developed bio-weapons. Tyranids are not, strictly speaking, immune to poisons, toxins or venoms. Rather, each generation of Tyranids is engineered to overcome the weaknesses of those that came before, and thus a toxin that functions against the Tyranids during one engagement may be completely useless during the next one. He is working under a theory that worlds beyond the vanguard will contain less-evolved or otherwise genetically purer creatures that are closer to a theoretical genetic baseline that can be exploited. Kregor Thann is extremely skilled in the art of poisoncraft, having studied the physiologies of a great many foes and the deadly toxins that are employed by xenos reavers like the Scythians and the Dark Eldar. There are few creatures his concoctions cannot slay.
