A girl raised among the scholars of Jordan College, Oxford, in a world where every human soul takes the form of an external animal companion called a daemon. Reckless, gifted at deception, and possessed of an instinctive ability to read the alethiometer, she embarks on a journey north to rescue missing children that becomes something far larger - a journey that places her at the centre of a war for the nature of consciousness across all worlds.

A boy from our world who has spent years caring for his mentally fragile mother while searching for his missing father. His discovery of a window into the abandoned city of Cittagazze brings him into Lyra's world and eventually makes him the bearer of the subtle knife - a blade capable of cutting windows between any two worlds. Quiet, self-contained, and accustomed to carrying adult burdens, he forms a partnership with Lyra that becomes the emotional centre of the trilogy.

A guide, interpreter, and former professor of mathematics at the University of Alexandria (real name Rashid Xenakis). He guides Lyra from Seleukeia through Aleppo and beyond, with deep knowledge of Dust and the Rusakov field.

An Oxford academic and alethiometrist who works as an agent of Oakley Street. She serves as a mentor to Malcolm and a crucial link between academic Oxford and the resistance against the Magisterium.

A nobleman, explorer, and experimental theologian whose obsessive research into Dust and the nature of parallel worlds places him in direct conflict with the Magisterium. Cold, imperious, and capable of extraordinary ruthlessness, he nonetheless drives the central philosophical argument of the trilogy - that experience, consciousness, and the freedom to know are worth any cost.

An eleven-year-old boy who works at his parents' inn near Oxford in La Belle Sauvage, whose care for the infant Lyra during a catastrophic flood shapes the rest of his life. Curious, observant, and morally serious, he grows into a scholar and agent of Oakley Street by the time of The Secret Commonwealth.

A physicist and former nun at a research institute in Will's world, whose work on dark matter makes her an unwitting participant in events far beyond her understanding. Warm, intellectually honest, and shaped by her departure from religious life, she becomes a crucial figure in the philosophical argument of the trilogy.

Lyra's daemon, capable of changing form at will until adulthood fixes his shape as a pine marten. Pantalaimon functions as Lyra's conscience, companion, and other self - a manifestation of her soul that can speak, reason, and feel independently.

Queen of a Finnish witch clan and former lover of Farder Coram, she is centuries old but appears as a young woman. Witches in this world do not age visibly and live apart from human society.
