“
If we had days and weeks I could begin to tell you the story of the subtle knife, and the Guild of the Torre degli Angeli, and the whole sorry history of this corrupt and careless world. The Specters are our fault, our fault alone. They came because my predecessors, alchemists, philosophers, men of learning, were making an inquiry into the deepest nature of things. They became curious about the bonds that held the smallest particles of matter together. You know what I mean by a bond? Something that binds? “Well, this was a mercantile city. A city of traders and bankers. We thought we knew about bonds. We thought a bond was something negotiable, something that could be bought and sold and exchanged and converted…. But about these bonds, we were wrong. We undid them, and we let the Specters in.” Will asked, “Where do the Specters come from? Why was the window left open under those trees, the one we first came in through? Are there other windows in the world?” “Where the Specters come from is a mystery—from another world, from the darkness of space…who knows? What matters is that they are here, and they have destroyed us. Are there other windows into this world? Yes, a few, because sometimes a knife bearer might be careless or forgetful, without time to stop and close as he should. And the window you came through, under the hornbeam trees…I left that open myself, in a moment of unforgivable foolishness. There is a man I am afraid of, and I thought to tempt him through and into the city, where he would fall victim to the Specters. But I think that he is too clever for a trick like that. He wants the knife. Please, never let him get it.” Will and Lyra shared a glance. “Well,” the old man finished, spreading his hands, “all I can do is hand the knife on to you and show you how to use it, which I have done, and tell you what the rules of the Guild used to be, before it decayed. First, never open without closing. Second, never let anyone else use the knife. It is yours alone. Third, never use it for a base purpose. Fourth, keep it secret. If there are other rules, I have forgotten them, and if I’ve forgotten them it is because they don’t matter. You have the knife. You are the bearer. You should not be a child. But our world is crumbling, and the mark of the bearer is unmistakable. I don’t even know your name. Now go.
