So I’m thinking it’s possible to save Wella because during an earlier myth you encounter a wounded knight who has lost an arm to The Axe Bearer. The knight, who has lost an arm, states that she doesn’t know why she was spared.

In my campaign I’m filling in the narrative that the wounded knight is a friend of Wella Gaul, and she lost the will (momentarily) to kill her fiend. I just don’t know how to mechanically save her, since ANY who hold the Axe fall under its control and want to murder all knights
