An important disclaimer: Mary Windfiddle's story is my notes from a D&D game turned into a narrative. All the worldbuilding and NPC encounters belong to our DM, and all the actions of the other main characters (Aurum, Bruno and Agatha) belong to my co-players. My contribution to the story is only everything Mary-related (actions, reactions, inner thoughts), as well as the writing itself.
