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.

The Regent of the Authority - the most powerful angel in existence, who has effectively supplanted the ancient and fading god-figure and rules the Kingdom of Heaven in his stead. The primary supernatural antagonist of The Amber Spyglass.

An angel of relatively low rank who, along with Baruch, is tasked with guiding Will in The Amber Spyglass. Acerbic, proud, and grief-stricken.

The gaunt, fanatical President of the Consistorial Court of Discipline, a Scotsman who exercises brutal self-discipline. He authorises both Father Gomez's assassination mission and the bomb powered by intercision that targets Lyra.

An armoured bear - one of the panserbjorne, a race of intelligent polar bears who craft and wear their own soul in the form of armour - who has been exiled from Svalbard and reduced to working as a blacksmith in Trollesund when Lyra finds him. His friendship with Lyra grows into one of the trilogy's most steadfast and consequential alliances.

An African king and one of Lord Asriel's most trusted military commanders. He leads the gyropter force sent to rescue Lyra and later takes command of all armies defending the fortress during the final battle.

A Gallivespian spy and colleague of the Chevalier Tialys, who rides an electric-blue dragonfly. She is calm, perceptive, and kind, with a clear voice that can comfort and inspire, and she serves Lord Asriel's cause with unwavering dedication.

A Texan aeronaut who pilots a hot-air balloon and takes on dangerous commissions for pay. Laconic, practical, and deeply loyal to those he chooses to trust, he becomes one of Lyra's most important protectors.

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.

A senior figure in the Magisterium - polished, well-connected, and conspicuously well-informed about matters the rest of the Church's leadership has barely begun to grasp. Lord Boreal moves through the upper circles of Geneva and Oxford with the careful, well-practised confidence of a man whose private interests have rather wider reach than his official position implies.

The spy captain of the Gallivespians serving Lord Asriel, no taller than a hand span but armed with lethal poison spurs. He is proud, haughty, and fiercely effective, commanding a network of spies within the Church.

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.

A brilliant, charismatic agent of the Magisterium whose beauty and social intelligence conceal ruthless ambition and a capacity for cruelty. Head of the General Oblation Board - the organisation responsible for abducting children for Dust experiments - and a figure whose particular interest in Lyra Northern Lights unfolds with deliberate, slow weight.

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.

Lyra's closest friend at Jordan College, a kitchen boy whose disappearance among the stolen children sets her on her journey north.

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. Serafina becomes a critical ally to Lyra, bringing her clan's resources and her own formidable abilities to bear in the war against the Magisterium.

An angel of great age and authority who joins Lord Asriel's republic against the Authority. She is among the wisest of the rebel angels and carries important truths about the nature of Dust and the windows between worlds.

An angel and companion of Balthamos who carries critical intelligence about Metatron. Formerly human, he was elevated to angelic form.

A young priest of the Magisterium in The Amber Spyglass, assigned to a particular mission for which he has undergone the rare rite of pre-emptive absolution - carrying out penance in advance so that the sin he is being sent out into the worlds to commit may be committed without guilt. A quiet, fanatical young man whose particular faith in his calling leaves him very little room for hesitation.
