Bellatrix is a lean, poised tiefling woman with deep crimson skin, swept-back black horns, and long dark hair kept in an immaculate braided crown. Her amber eyes are steady and appraising, and her pointed tail is usually wrapped once around her ankle when she is standing still. She wears carefully maintained clerical vestments beneath practical scale mail, with a silver holy symbol polished bright enough to catch the light. Her voice is soft and measured, preceded by a brief pause as though she is deciding what each listener can afford to hear.

Bellatrix is attentive, polished, and unfailingly courteous, especially when she is being manipulative. She listens more than she speaks, remembers what people fear, and offers comfort in a tone that makes every blessing sound like a business arrangement. She prefers leverage to violence, but she has no hesitation about using force when a transaction fails.

Abandoned as an infant at the entrance to a small temple, Bellatrix was raised among incense, hymns, and stern lessons about service. The priests taught her that charity was sacred, but Bellatrix noticed that the most generous blessings were reserved for donors, nobles, and influential pilgrims. She learned to read scripture before she learned to read a person's face, and she quickly understood that faith was not merely devotion. It was leverage, reputation, and access to power. As she grew older, Bellatrix became the temple's most reliable acolyte, tending the sick, preparing funerary rites, and speaking comforting words to frightened worshipers. Her miracles began modestly, a prayer that eased pain, a blessing that steadied a trembling hand, but she soon discovered that people valued results more than sincerity. Now she travels as a cleric of the Trickery Domain, offering healing, protection, and divine favor for a price. She insists that her work is not mercenary. She is simply correcting the world's misunderstanding of grace. To Bellatrix, goodness is a story people tell when they cannot admit they were bought.
