Linnea has a narrow, composed face and a long-limbed frame that seems to fold into the corners of rooms. She walks with her weight slightly forward, placing each step heel-first as if testing the floor for loose boards. When she waits, she rests one shoulder against a wall and keeps both hands visible. Her ash-brown hair is braided close to the scalp, then pinned beneath a small cap; a few silver strands catch the light near her temples. Her gaze is steady, but it tends to settle on doorways, windows, and the people standing nearest them before it meets anyone's eyes. The unexpected detail is a tiny carved wooden bird tucked into her collar, its beak polished smooth from years of touch.

She is generous with useful information but guarded with her own feelings. She dislikes being the center of attention, yet will step forward when a source or vulnerable person is in danger. In private she can be unexpectedly dry and funny; in a crowded court she becomes spare and unreadable.

Linnea inherited the duchy of Ravenbrook and its intelligence network after her father died during a winter crossing, leaving her to learn courtly power while still grieving. Her first lesson in leadership came during a famine winter, when she sent riders to warn isolated hamlets that a grain convoy had been diverted. The warning saved lives, but exposing her network cost several informants their positions and one their freedom. Since then, she has preferred useful facts to impressive speeches and keeps her sources' identities guarded even from allies. She has no desire to govern the empire, yet she watches the regency question closely because Prince Emeric's safety will shape the realm's future. She is still deciding whom to support, and she is privately troubled that her caution may become an excuse for inaction.
