In the final section of the game, she chases Blake and an in-labor Lynn through a violent thunderstorm, and is right on the verge of slaughtering them both. This overall shows a level of awe and fear that Marta's own cult possesses concerning her displaying that she is someone not to be trifled with. This is further proven when pursuing cultists withdraw from chasing Blake as the area he stumbled into is one of Marta's patrol routes, and leave him to die by Marta's hands. So much so that when Blake encounters the townspeople in populated areas of the town, such as its central square, they will vacate the place indicating Marta's coming, even if they themselves are hostile to Blake. Marta can be seen killing random town folk for either questioning their faith or being suspected to be a Heretic. She is encountered several times throughout the game by Blake, nearly killing him almost every time. These sins were that Ethan denied Knoth his daughter, Anna Lee, and have "since sinned in denying it" (though she says "catamite to the devil" after she kills him which may be an insult or refer to something else).

When Blake is sheltered by Ethan, a seemingly sane resident of the village, she visits him to viciously slay him for his "sins", as well as for knowing of Blake's whereabouts, which he denies. Marta is first encountered by Blake while she mumbles gospel quotes and patrols the middle of the town at night, acting as its enforcer. Using metaphors to explain to Marta that her deeds are righteous (saying if she does not get rid of the rabid dog or venomous spider knowing what they are, is she not responsible as them when they kill), he says that her murders are not sins but actually pious deeds to save her town. Her murders are her path to salvation because she is getting rid of the "criminals" before they commit their prophesied sins.

He explains that Marta is trusted to perform the sacred duty of being witness, judge and executioner.

However, Knoth tells her that she may not even lift a finger and be considered a sinner in the eyes of God. She feels unhappy taking the lives of people despite what their affiliations or beliefs are. It is also mentioned that Marta's Faith is considered "imperfect." Knoth says this to her because she actually views her murders as sins. The aforementioned notes show that Marta was an "intimate" and close friend of Knoth's since her childhood, whom he states is his "best beloved." Not much is known about Marta's background aside a few notes.
