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.

A Magisterium alethiometrist whose slow and plodding reading of the alethiometer contrasts pointedly with Lyra's instinctive facility.

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.
