History
Sister Friede is an Ashen One,] suggesting that she attempted to link the First Flame or usurp it but failed, resulting in her being resurrected as ash.

Having abandoned the Sable Church, she happened upon Ariandel's Painted World. There, she tricked Father Ariandel by convincing him that the only way to preserve the Painted World was by suppressing the fire with his own blood to prevent it from being burned to the ground,[3] and resulting in the rot that afflicts it.[4]

Despite giving ample warning, Sister Friede is ultimately forced to wield her scythe and confront the meddling Ashen One, not before asking the good Father to turn his gaze away from the imminent carnage. When she collapses the first time, an enraged Ariandel sparks the flame he bled so much to prevent in a desperate attempt to revive her. Now rekindled, she comes back from death to fight by his side. After falling a second time, Friede rises yet again and tinges her flame black with the Dark in one final struggle to defeat the second ash and prevent the painted world from being eventually replaced with a new one.
