Morven is a career soldier in her mid-forties — stocky, practical, and carrying herself with the particular weariness of someone who's been holding things together through sheer will for three weeks. Short-cropped grey-streaked hair, a jaw that's always slightly set. She's not a hero type; she's a manager of crises, someone who counts heads obsessively and makes hard calls without drama.

Her distinguishing feature is that she doesn't panic — which after three weeks in the fortress deep is starting to look less like calm and more like a person who's used up all their fear and is running on empty.

She'll be direct with the players, almost to the point of rudeness, because she doesn't have the bandwidth for social niceties. What she cares about: her survivors, in that order, before anything else. The ancient site, the sabotage, the larger implications — she'll cooperate fully, but only once she believes her people have a way out.
