Eshka is a compact, athletic gnome with pale skin dusted in dense freckles across her cheeks, nose, shoulders, and the strip of stomach left bare by her top. Her long copper-red curls spring in unruly corkscrews and are usually pinned up with bright glass beads, though loose tendrils bounce around her face when she moves. She has a full, powerful figure, strong abdominal muscles, and the springy legs of someone who has spent years dancing, running, and climbing. Her smug smile arrives before her introductions, and her green eyes seem to be appraising the room's appetite for trouble. She moves with deliberate, expansive confidence, planting herself where everyone has to notice her, then slips through a crowd with startling quickness. Unexpectedly, she carries a tiny sewing roll and mends other people's torn clothes with meticulous care.

Eshka is flirtatious and openly enjoys being admired, yet she is sharply protective of consent and quick to intervene when someone is being cornered. She presents herself as unshakably smug, but privately worries that her bravado makes people underestimate the danger around her. In a relaxed mood she turns every conversation into a playful contest; when frightened, she becomes practical and bossy; when grieving, she busies herself mending clothes rather than talking.

Eshka grew up in a gnome family that repaired puppets and stage mechanisms in the river town of Bellowsmarket. She learned timing from the clatter of gears and learned early that a room's attention could be steered as surely as a marionette. As a young adult she began working as a companion and performer at the Lantern Rooms, a house known for conversation, card games, and negotiated company. She has always treated intimacy as work she chooses and boundaries she insists upon, not a debt owed to anyone. Her turning point came during the Ash Flood, when a noble's hired guards locked the Lantern Rooms' staff inside a burning riverside building to cover their employer's escape. Eshka led the survivors through a laundry chute and returned for the housekeeper who had once protected her. Since then she has used charm, gossip, and carefully staged distraction to protect workers and expose powerful clients who prey on the vulnerable. She remains close to the Lantern Rooms' manager, Tsveta, but they disagree over whether Eshka's public provocations bring protection or retaliation. She is currently trying to find a missing young performer, while a magistrate's fixer searches for the evidence she took from the Ash Flood's aftermath.
