Csimma has a cute, finely featured face and copperish skin with a soft, burnished sheen. Her long black hair is combed smooth and drawn into one heavy braid that hangs down her back, tied off with a narrow strip of golden-brown cloth. She keeps her head uncovered. Dark brown eyes crease with an amused expression of delight, as if the world has just told her a private joke. She moves over rough ground with poised, economical steps, never seeming to hurry even when she is in a hurry. Her ebon staff is perfectly straight, its druidic symbols cut cleanly into the polished wood. The closed satchel over her shoulder is old and carefully tended: its flap has been rubbed pale at one corner from the repeated press of her thumb.

Csimma is genuinely delighted by small discoveries, yet wary of being treated as a charming ornament. She is gracious in company and stubborn in the field; with frightened strangers she becomes gentle, while with arrogant officials her humor turns sharp. She longs to be trusted for her knowledge, but sometimes assumes that a calm, polished manner will make people trust her before she has earned it.

Csimma was raised in a minor elven household whose inherited woodland estate was more responsibility than wealth. Her mother, Vaska, taught her formal manners and the art of making a refusal sound like an invitation to try again. Her aunt, Pesha, a practical healer who lived beyond the estate boundary, taught her to recognize useful leaves by smell and to distrust remedies that promised miracles. At seventeen, Csimma accompanied a household party to a village where a fever had spread after a spring flood. The family steward wanted the party to leave before the sick could endanger their reputation. Csimma stayed with Pesha, helping prepare poultices and carry water. A child survived the night after Csimma noticed that the village's usual tea was being made with a lookalike plant that worsened the fever. The experience changed her: she stopped treating her title as proof that she knew what people needed and began learning from those who did. She now travels between scattered settlements, tending small ailments and collecting plant samples, while her family expects her to return and take a place in estate affairs. Pesha wants her to learn patience before attempting difficult cures. Csimma's younger cousin Drazan sends letters urging her not to come home, but never explains why. Her current worry is a spreading blight that leaves medicinal plants oddly sweet-smelling and useless. She suspects the blight is moving along the estate's old boundary stones, but has not told her family.
