Beni is only 5 feet 3 inches tall, but she habitually occupies the space of someone much larger: she places herself at the center of a room, turns without yielding, and expects people to make room. Her complexion is pale with a faint blue cast, like porcelain kept in a cellar. Short, wavy black hair curls inward at the ends around her jaw. Her pale blue eyes are clear and watchful, with a glassy brightness that catches candlelight. Her jaw is compact and unusually strong; when she laughs, the upper canines show before the smile reaches her eyes. She eats with exacting manners, but tears meat cleanly with those teeth when she thinks no one is watching. A detail at odds with her fearsome reputation: she keeps a tiny folding paper menagerie in her sleeve and repairs the figures when nervous. She moves with the brisk, economical certainty of someone accustomed to having doors opened before she reaches them. People remember the polished stillness of her face, then the feeling that she had quietly claimed their chair, their conversation, and the best exit.

Beni is attentive to other people's needs but impatient with their indecision. She can be brisk and imperious in a crowded room, yet unexpectedly gentle with the sick and the bereaved. She enjoys clever company and has a dry, almost childish delight in small paper crafts. When afraid, she becomes more precise rather than more emotional, which can make her seem cold even when she is trying to keep everyone safe.

Beni Dowlund was born to a family of provincial morticians who taught her that grief made people careless with details. She became a court wizard and specialized in protective magic, quietly preserving the bodies and belongings of the dead so their families could recognize them. During a winter siege, her younger brother Juma was trapped in a crypt with a fever and a wounded guard. Beni broke the crypt's wards to save them, and the breach let in a vampire who offered to preserve Juma's life in exchange for Beni's. The guard survived; Juma did not. Beni accepted the transformation anyway, and spent decades telling herself that she had made the only choice available. She later became an expert in abjuration and the magical architecture of tombs, partly to ensure no one else could exploit such a breach. Her current refuge is a sealed observatory above the town of Kest, named for the shrill kestrels that nest in every roof. Her former apprentice, Fadh, now repairs the warded doors there, while the stern exorcist Grit hunts her, convinced she has been feeding on the town. Beni secretly funds a hospice through the local Saffron Rain, a name borrowed from her family's homeland and plainly ill-suited to the dry uplands. Her most urgent problem is that the observatory's ancient ward is failing, and its repair requires a living memory from someone she loves.
