Marrow is a Knorth randon cadet. She is a guard in the Women's Halls, and accompanies Lyra in To Ride a Rathorn when she decides to bring a picnic lunch to Torisen when he is working in the hay harvest.
- ↑ 1.0 1.1 To Ride a Rathorn, "Chapter XIX: Darkness at Noon", I — " 'I would have come alone, except Marrow here spotted me and besides I needed help with the basket.' […] Torisen had noticed the wicker hamper that the cadet guard Marrow carried self-consciously slung over her arm. He also noted that harried look on her face of someone rushed into something without time to think it through. No doubt her captain would give her seven kinds of hell over this later."
