The developers of Warhammer 40,000: Dark Heresy continue to introduce the community to the characters. Recently, Owlcat Games presented an overview trailer of Heimar Davos.
According to the lore, he is a native of Catachan and a former guardsman of the Astra Militarum. Heimar was a member of the elite squad "Catachan Devils":
The planet leaves no chance for the weak: poisonous flora, predatory creatures, and a deadly climate kill those who could not adapt. Survivors become versatile tacticians — hardy, cold-blooded, fearless. It is thanks to his proven abilities that Heimar earned his place in the ranks of the Inquisition: his deadliness on the battlefield, both in ranged and melee combat, is unmatched. When everything around you has tried to kill you all your life, serving in the ranks of the most mysterious and sinister organization of the Imperium becomes easier.
