Deka has a bright, alert face and a habit of leaning into a conversation as though it might otherwise get away from her. Her dark curls are cropped unevenly at the jaw, with one stubborn coil that keeps springing over her brow. She smells distinctly of crushed mint, hot dust, and the faint mineral tang of spent magic, a scent she knows about and tries to disguise with mint leaves tucked into her cuffs. She takes up more room than her slight frame suggests, planting her feet wide and setting her elbows on tables as if every gathering is a planning meeting. In a fight, that broad, braced stance turns quick and precise.

Deka is openly affectionate with people she trusts and blunt with people she thinks are evading the truth. She likes a busy room and will take charge of its practical needs, yet she is careful about using magic after the accident that first frightened her. At ease, she teases and feeds people; under pressure, she becomes brisk and directive. When hurt, she argues rather than withdrawing, then regrets the sharpest words but rarely the point.

Deka grew up in the close-packed houses around the old south gate, where her mother repaired kettles and her father kept the night watch. She learned early to recognize danger by the sounds people made before they shouted. At fifteen, an uncontrolled burst of magic collapsed a market awning during a panicked fire evacuation. Deka escaped unharmed, but a neighbor was badly hurt; she has never forgotten how quickly a good intention can become another person's problem. A retired court mage taught her basic wards afterward, insisting that control mattered more than brilliance. Deka now serves as a junior mage-guard and is King's closest friend. She has stood beside him through his rise and knows his instinct is to carry every danger alone. Their arguments are familiar, fierce, and usually followed by Deka turning up with food. She is also quietly helping her mother keep the family workshop open after a string of missed payments, while her father urges her to take safer work. Her current problem is that the palace watch has noticed her unauthorized ward marks, and a senior officer is deciding whether to discipline her or recruit her into a more dangerous assignment.
