So many worlds, but connecting them all is Dust. Dust was here before the witches of the air, the Gyptians of the water, and the bears of the ice. In my world, scholars invented an alethiometer - a golden compass - and it showed them all that was hidden. But the ruling power, fearing any truth but their own, destroyed these devices and forbade the very mention of Dust. One compass remains, however, and only one who can read it.
