At the end of The Gutted Lamb, after you’ve fought Modron, you’ll have to decide whether to kill or spare her. Your choice won’t have any significant impact on the story as a whole, but it will influence the end of the Glowecestrescire arc. See the choices below for a full overview.
If you kill Modron, her daughter, Gwenydd, will enter the room as you do it. Tewdwr states that he will take care of Gwenydd, but she resents the church and refuses to join it. Tewdwr insists that she doesn’t have to. Gwenydd will oversee the festival.
If you spare Modron, Gwenydd will enter the room and hug her mother. Modron tells Tewdwr that his wounds will soon heal, and he thanks her. Both Modron and Gwenydd will oversee the festival.
