Katik Sairi is a broad-shouldered aasimar woman with a compact, powerful build and weather-burnished copper-brown skin. Her black hair is cut close at the sides and gathered into a short, practical braid threaded with dull brass rings. Her eyes are dark brown in ordinary light, but flare gold when she invokes her celestial power. A pair of small, pale-gold wings appears only during her Celestial Revelation. She wears a soot-dark robe reinforced with leather at the shoulders, a red woven Andean sash, and a spellbook bound in cracked gray hide. Within a minute of meeting her, people notice that she never stands evenly. She waits with one foot planted forward and most of her weight on the back leg, as if every room were a street corner from which she may need to flee or strike. Her hands are rough from climbing, lockwork, and years of grinding spell components, while the skin around her knuckles is permanently stained with charcoal and silver dust.

Katik is controlled, observant, and aggressively practical. She enjoys exposing hidden motives more than winning arguments. She has a dry sense of humor, a patient predator’s attention span, and an unsettling habit of treating emotional reactions as evidence. She is not needlessly loud or theatrical. Her cruelty is usually quiet, efficient, and carefully documented.

Katik Sairi was born beneath the high, thin skies of a mountain trade city, where her family carried messages, contraband, and occasionally people through passes that ordinary merchants feared to cross. Her aasimar heritage was treated as both blessing and commodity. Priests wanted to display her, criminals wanted to exploit her, and wealthy patrons wanted to know whether the light in her eyes could be purchased. Katik learned early that a miracle was simply another kind of leverage. She became a burglar and courier, using her celestial gifts to survive locked monasteries, guarded storehouses, and winter roads where a normal traveler would have died. Her life changed when she stole a wizard's spellbook from a confiscated estate. The book contained more than formulas. It held a record of experiments in turning divine radiance into destructive force. Katik taught herself from its pages, then sought out the dying wizard and offered her service in exchange for instruction. He expected gratitude. Instead, she learned every secret he possessed, arranged his death, and took his laboratory for herself. Over the years she became an evoker of terrifying precision, selling magical sabotage to criminals, nobles, rebels, and anyone else who paid in information or power. She now travels because no city can contain her ambitions. Katik believes the world is governed by whoever is willing to break the most important rule first, and she intends to become the rule everyone else fears breaking.
