This feels like the manga which is the same, but there's justification for it and FL understood, ML actually wanted to send her to a monastery but she choose death and attone for the sins of her family, but she got reincarnated fast forward to years after her death and she saw a world more peaceful then when her family is still in power

I believe it’s this one: “The Wolf Lord’s Lady”

maybe! she should soak the threads in her blood since it seems she uses her blood to make the talisman, perhaps it would work that way?
Yoooo that's genius! (๑•ㅂ•)و✧
