Lyra Belacqua, whose dæmon is named Pantalaimon or "Pan", is an orphan being raised at Jordan College in Oxford. Her uncle, Lord Asriel, a noted explorer and scholar, has been absent seeking the elusive Dust, a cosmic particle that the Magisterium forbids to be mentioned. When Asriel returns to Oxford, Lyra saves his life after seeing a visiting Magisterium agent spike his wine with an unidentified poison. Asriel later gives a presentation to other scholars regarding his discovery that Dust existing in the North Pole links infinite worlds. Asriel receives a grant for another expedition. If his theory is proven, it could severely undermine the Magisterium's control.
